Qadri1, Aqib Hussain Mir2 1,2Department of Mechanical Engineering, National Institute of Technology, Srinagar, J&K, India, 190006 ---------------------------------------------------------------------***--------------------------------------------------------------------- Abstract – Theoretical analysis has been carried out for determining the hourly optimum tilt angle and Hourly total solar radiation on optimum tilted surface of nano fluids in flat plate collector year for Srinagar city (Latitude =34˚), Jammu and Kashmir. The water based Copperoxide(CuO)nanofluidis used as a working fluid. Amathematical modelandaprogram, written in MATLAB code were used. The results showed that the monthly optimum tilt angle for December, one of the coldest winter month of Srinagar city, is found to be 87˚ where the hourly solar radiation incident on the collector surface obtained for noon is 2.19 MJ/m2h. Also the monthly total solar radiation, incident on the collector surface south facing, changes throughout the year with its maximum valueof2.492 MJ/m2 h in July (summer month) and minimum value of 1.416 MJ/m2 h in December (winter month). Key Words: Theoretical, Latitude, Flat plate collector, CuO, Mathematical Model, MATLAB, Optimum tilt angle.. 1. INTRODUCTION The flat platecollector formsthe heartofanysolarenergy collection system designed for operation in the low temperature range, from ambient to 60˚C, or the medium temperaturerange, fromambientto100˚C.Asolarcollectoris a special kind of heat exchanger that transfers the radiant energy of the incident sunlight to the sensible heat of a working fluid-liquid or air.Theinventionoftheliquidheating flat plate solar water heater is credited to H.B Saussure, during the second half of the seventeenth century [4].Flat Plate collectors have the following advantages over other types of solar energy collectors: (i) Absorb direct, diffuse and reflected components of solar radiation (ii) Are fixed in tilt and orientation and, thus, there is no need of tracking the sun, (iii) Are easy to make and are low in cost, (iv) Have comparatively low maintenance cost and long life, (v) Operate at comparatively high efficiency. 1.1 Objectives of the Study The objectives of the current study are: 1. To develop a mathematical modelandMATLABCode for evaluating various parameters. 2. To determine hourly optimum tilt angles,β_opt, for the average day of each month in the year for Srinagar city (Latitude =34˚), Jammu and Kashmir. 1.2 LITERATURE REVIEW Morcos [1] developed a mathematical model for calculating the total solar radiation on a tilted surface. The model was then used to determine optimum tilt angles for a flat plate collector and the optimum tilt angle and surface azimuth angles for concentrating solar collectors on a daily basis, as well as for a specified period. Saraf et al. [2] developed a mathematical model for calculating the useful energy gained by a flat plate collector under various operating conditions. The model was then used to determine the optimum tilt angles for a typical collector in Basrah on a daily basis, as well as on the basis of a specified period. The optimum tilt angle was found by searching its value for which the useful energy gained bythe collector is a maximum for a particular day or a specified period. From the results, it was observed that changing the tilt angle eight times in a year determines the useful energy in Basrah near its value which is found by changing the tilt angle daily to its optimum value. Choi and Eastman [3] studied low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in many industrial applications. They proposed that an innovative new class of heat transfer fluids can be engineered by suspending metallic nanoparticles in conventional heat transfer fluids. The thermal conductivity of metallic liquids is much greater than that of nonmetallic liquids. Therefore, the thermal conductivities of fluids that containsuspendedsolidmetallic particles were enhanced when compared with conventional heat transfer fluids. Yimin and Wilfried [4] described nanofluid as a solid-liquid mixture in which metallic or nonmetallic nanoparticles are suspended. The suspended ultrafine particles change transport properties and heat transfer performance of the nanofluid, which exhibits a great potential inenhancingheat

The mechanismofheattransfer enhancementof the nanofluid was investigated. Based on the assumption that the nanofluid behaves more like a fluid rather than a conventional solid-fluid mixture, two different approaches for deriving heat transfer correlation of the nanofluid were developed. 2. Methodology 2.1 Estimation of Heat transfer coefficient and Nusselt number Liu and Jordan [1] considered the solar radiation on the tilted surface, IT, as the sum of the beam radiation, isotropic diffuse radiation, and solar radiation diffuselyreflectedfrom the ground and obtained the equation for anhourasfollows: The tilt factor for beam radiation is the ratio of the beam radiation flux falling on a tilted surface to that falling on a horizontal surface. For an hour, it is given by: For the case of a tilted surface facing south is givenby: Where and are site latitude angle and solar declination angle. Cooper [2] has given the following simple relation for calculating the declination angle, The tilt factor for diffuse radiation is the ratio of the diffuse radiation flux falling on the tilted surface to that falling on a horizontal surface .the value of this tilt factor depends upon the distribution of diffuse radiation over the sky and on the portion of sky dome seenbythetiltedsurface. Assuming that sky is an isotropic source of diffuse radiation, we have for a tilted surface with a slope , Since is the radiation shape factor for a tilted surface with respect to the sky, it follows that is the radiation shape factor for the surface with respect to the surrounding ground. Assuming that the reflection of the beam and diffuse radiations falling on the ground is diffuse and isotropic, and that the reflectivity is , the tilt factor for reflected radiation is given by Liu and Jordan suggested values of diffuse ground reflectance of 0.2 when there is no snow and 0.7 when there is fresh snow cover. The total solar radiation on the horizontal surface, I, Can be expressed as: Where constants are given by: The hour angle which is an angular measure oftimeandis equivalent to 15˚ is given by The convention of measuring it from noon based on local apparent time, being positive in the morning and negativein the afternoon. The hour angle corresponding to sunrise or sunset( )ona horizontal surface can be calculated from the equation: The above Equation yields a positive and a negative value for , the positive value corresponding to sunrise and the negative to sunset. The monthly mean daily solar radiation intensity on a horizontal surface, H, isestimatedaccordingtotheAngstrom model. where is the monthly average global radiation on horizontal surface, is the monthly average daily bright sunshine hours, is the maximum possible monthly average daily sunshine hours or the day length, a and b are constants, and is the monthly average daily extraterrestrial radiation (MJ/m2 day) which can be expressed as

Using the above relations, maximum total solar radiation on an optimum tilted surface is calculated for the specific days of the year. The collector location considered in this study is at Srinagar, Jammu and Kashmir (Latitude=34˚N, Longitude=74˚50’, Altitude=1586m above sea level). 3. Results and discussion The following results were obtained in MATLAB program using data of Srinagar city, Jammu & Kashmir. 3.1 Hourly Optimum Tilt Angle The hourly optimum tilt angles, βopt, for the average day for each month in the year were computed based on the geometric data of Srinagar city (Latitude = 34˚N, Longitude = 74˚50’E and altitude = 1586 m above sea level)inJammu& Kashmir by using MATLAB program. Srinagar has four distinct seasons. The average temperature in Spring (March to ending April), Summer (May to August), Autumn (September to November) and Winter (December to February) seasons are 15˚C, 30˚C, 25˚C, 5˚C respectively. Fig -1: Variation of hourly optimum tilt angle for the average day for each month in the year. Fig.1 showsthevariationhourlyoptimumtiltangleforthe average day of each month in the year with daytime from 7a.m-5p.m.The flat plate solar collector is facing south in Srinagar. The value of the hourly optimum tilt angles increases with daytime before solar noon and reaches maximum at noon during the months of April-September as depicted from figure. The hourly optimum tilt angles decreases after solar noon during the months of April- September and the reverse trend of the curve occurs during the months of October-February. The maximum and minimum optimum tilt angle varying in the range of (50˚to82˚) and (-20˚to-2˚) occurs in December and June respectively. It is noticeable that the optimum tilt angles varying with the daytime for the average day for the months of May, June, July are observed to be negative. When the tilt angle is negative, the collector is facing the north and whenit is positive, the collector is facing the south. The hourly optimum tilt angle for the month of March remains almost constantthroughoutdaytimewhichisapproximatelyequalto the latitude angle of Srinagar (34˚N). The optimum tilt angle fora flat platesolar collector facing south is 82˚ in December. The optimum tilt angles for the month of May to August are observed to be negative values. According to the results, the collector must be set north facing during those months. In this study, all the negative values of the optimum tilt angle were considered zero (horizontally). This is due to the fact that the practical orientation for the collector installed in the northern hemisphere is south facing with the positive tilt angle. The monthly optimum tilt angles were used for estimating the monthly total solar radiation, IT , for an hour on the tilted collector surface.

The set of Equations given in methodology section were used in the MATLAB program for this computation. Fig. 2 shows that the variation of hourly total solar radiation, IT, on optimum tilted surface for the average day of each month. The value of total solar radiation increases with daytime and reaches its peak valve at solar noon. The highest hourly solar radiation (3.323MJ/m2h) occurs in July at noon, and the lowest one is 2.199MJ/m2 h in December at noon.

Conclusions The present study analyzed theoretically the efficiency of CuO-water nanofluid based flat plate solar collector for water heating applications using the MATLAB program. Following conclusions can be drawn from the currentstudy: 1. Hourly optimum tilt angles, β_opt, for the average day of each month in the year has been determined for Srinagar city (Latitude =34˚), Jammu and Kashmir. The monthly optimum tilt angle for the collector changes throughout the year, itistonotice that the monthly optimum tilt angle is the average of the hourly optimum tilt angles for the average day of each month in the year. The monthly optimum tilt angles are found to be negative for the months of May to August and they are considered zero for the south facing solar collector. The monthly optimum tilt angle for December, one of the coldest winter month of Srinagar city, is found to be 87˚ where the hourly solar radiation incident on the collector surface obtained for noon is 2.19 MJ/m2h. 2. The monthly total solar radiation, incident on the collector surface south facing, changes throughout the year with its maximum value of 2.492 MJ/m2 h in July (summer month) and minimum value of 1.416 MJ/m2 h in December (winter month).
