Veröffentlicht am

Fire safety is one of the most important factors to consider when designing a car park. In this webinar, we explain how CFD simulations can help engineers to virtually test and optimize HVAC systems and fans for smoke control in case of fire.

Smoke Control in a Car Park with Cloud Based CFD

  1. 1. SMOKE CONTROL IN A CAR PARK WITH CLOUD-BASED CFD Milad Mafi
  2. 2. Milad Mafi Product Marketing Manager With more than 10 years of professional experience with engineering simulation and motorsport aerodynamics, Milad manages, grows and supports relationships with key business and educational partners and presents webinars covering CFD and FEA.
  3. 3. 1. Benefits of Using Simulation 2. Introduction to SimScale 3. Smoke Control and CFD 4. Live Demonstration 5. Results Summary 6. Q & A
  4. 4. WHY SHOULD I CARE ABOUT SIMULATION? Depending on focus: ● Lower cost ● Lower failure risk ● Lower weight ● Increase product lifetime ● Increase “performance” Make better design decisions earlier. Depending on role: ● Designer: Rough early estimation on product strength and durability on multiple design variants ● Engineer: Digitally test/validate the design before expensive physical testing
  5. 5. ACCELERATE YOUR DESIGN PROCESS Easily test performance, optimize durability or improve design efficiency with cloud-based simulation.
  6. 6. ALL-IN-ONE Structural mechanics, fluid dynamics, and thermodynamics. REAL-TIME SUPPORT Chat, phone and email. Consultancy, webinars, and training. COLLABORATION Join the community, benefit from public projects, and share know-how. FAST & EASY Get results faster on any device thanks to cloud technology. COST-EFFICIENT Start risk-free without an upfront investment. SECURE High security with government-approved Advanced Encryption Standard (AES).
  7. 7. SMOKE CONTROL IN A CAR PARK WITH CLOUD-BASED CFD How can you optimize HVAC SYSTEMS for SMOKE CONTROL in CAR PARKS with CFD?
  8. 8. ● Both day-to-day pollution and emergency smoke need to be safely and effectively ventilated. ● To keep escape routes clear and allow fire fighting crews easier access to the fire. ● Toxic gases are hazardous for occupants. THE IMPORTANCE OF SMOKE CONTROL IN CAR PARKS
  9. 9. WHY CFD FOR SMOKE CONTROL? Design Faster ● Investigate a variety of scenarios in parallel ● Avoid time-intense experiments Design Better ● Enable ‘performance-based’ design, not prescriptive ● Investigate many scenarios virtually to gain confidence ● Risk assessment & escape route planning Design more cost-efficiently ● Avoid over-designing/spending too much on unnecessary components ● Replace expensive experimental investigations
