CFD Analysis - A Cost Saving Measure for Building Owners

by dfwcgi on Nov 15, 2009

Traditional methods of designing HVAC systems normally rely on an engineer's experience, calculations and "rule of thumb" techniques as well as some empirical relationships. The limitation to this is that each building is unique in terms of its geometry, use, heat gains, personnel, location, etc. and therefore favorable experiences on one project cannot necessarily be applied to another. There is also the tendency to add margins into the design to compensate for these approximations. Ultimately, margins can be added on to margins with the result being a system over designed for the purpose it was originally intended.   Airflow modeling or CFD Analysis allows for the study of airflow direction, temperature, and pressure along with the optimization of air delivery. In short, CFD Analysis provides the following advantages:   Design Accuracy - To scientifically predict airflow patterns, temperature and contaminant spread as opposed to relying on an individual's...Read More >>
