2. The Aims of the Project
Estimating
Evaporation from
Water Surface
Water Body (WB)
Atmospheric
Boundary Layer
(ABL)

3. Water Body (WB)
• Heat Storage (Budget)
• WB’s Properties
(Shape,Turbidity, Fetch, etc.)
• Water Flow & Heat Transfer
• The Effect of Meteorological
Parameters and Surroundings
Measurement ?
or
Simulation?

4. CFD-WB
• CFD : Computational Fluid Dynamics
Geometry & CFD Computational Grid (Mesh)
Lake Binaba
Generated (Final) Bathymetry (stl) of
Lake Winkogo

5. Results (CFD-WB)

6. Atmospheric Boundary Layer (ABL)
• Airflow & Turbulence
• Momentum, Mass and Heat Exchange (ABL-WS)
• Heat and Mass Transfer
• Internal Boundary Layer (Roughness, Temperature, Wetness)
• Stability Conditions (Neutral, Stable, Unstable)

7. CFD-ABL
• Turbulence Models
• Buoyancy Effect

8. Results (CFD-ABL)

9. Results (CFD-WB)

10. Parallel Computing
• Model Should be Run in Parallel
• Decomposing, Reconstructing, etc.

11. Parallel Computing
A graphical representation of Amdahl's law. The speed-up of a program from parallelization
is limited by how much of the program can be parallelized. For example, if 90% of the
program can be parallelized, the theoretical maximum speed-up using parallel computing
would be 10x no matter how many processors are used.

12. Computational Resources
PC (6 CPUs, 24GB
Memory)
HPC03(Remote Sensing
