Experimental and Theoretical Car Flow Investigation

During the past few years substantial advances have been made in reducing the drag of automobiles. Future improvements are becoming increasingly difficult to achieve; for this reason more-advanced flow investigation methods are required.

This paper shows some results of flow analysis performed using two methods. The first is experimental and is based on car-wake flow surveying; the second is computational and is based on inviscid flow calculations simply corrected for viscous effects.

The two methods may be usefully combined.
