The following document includes part of a detailed simulation-vs.-experiment study designed to examine the ability of Flow Design to serve as a virtual wind tunnel for automotive design. The “experiment” in this case was a series of scale-model wind tunnel tests measuring drag and surface pressure over a range of air velocities. A battery of simulations was then run in the standalone version of Flow Design to reproduce the tests and investigate the accuracy of the tool. The results herein will focus specifically on performance in predicting drag.
