- 5. 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

- 12. SMOKE CONTROL IN A CAR PARK WITH CLOUD-BASED CFD How can you optimize HVAC SYSTEMS for SMOKE CONTROL in CAR PARKS with CFD?
- 13. ● 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
- 14. 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
