Experimental determination of drag coefficient on different automobiles geometry

الملخص EN

The undertaken research deals with an experimental determination of drag coefficient for five car models.

Experiments were run within a subsonic aspiration wind tunnel, covering an air speed up to 33m / s.Drag coefficients of 0.45, 0.39, 0.53, 0.34 and 0.68 for Mercedes SEL300, Hyundai, Toyota, Pajero, and Mini-Bus models were obtained respectively.

The flow field around the pre-quoted models with a qualitative description about the flow visualization for car models using a subsonic smoke wind tunnel has been accomplished.
