IDAC have automated the analysis procedure so that new geometry supplied by WSP can be input very quickly and there is a quick turnaround of results. As such, IDAC have been able to carry out a great many of these analyses for WSP Environmental and they have proved to be very valuable design tool. The analyses are quick and cheap compared with wind tunnel testing, and have provided WSP with significant cost and timesavings.
CFD is becoming increasingly popular as a tool for predicting air flows and is particularly effective for assessing internal conditions such as ventilation air flow. Choosing an environmental system to control the indoor climate without assessing its suitability can be costly. IDAC are able to use the CFD technology within ANSYS to simulate HVAC (Heating Ventilation and Air Conditioning) problems, so that the performance or suitability of a HVAC system can be established.
Another similar application of the CFD technology within ANSYS is to analyse Nitrous Oxide (NOx) problems. Nitrous Oxide emissions from cars in an enclosed space such as a car park can be a real problem. CFD can be used to assess out where best a ventilation system is to be situated for the most effective ventilation of nitrous oxide emissions from cars in car parks.
