An Investigation into pressure variation of fluid over a car surface

Mushtaq Ahmad Rather, Qaiser Bashir, Owais Ahmad Beigh

Abstract


The early attempts to streamline cars were made according to aeronautical practice and by adapting shapes from naval architecture.These failed due to two reasons.First, the benefits of aerodynamics were simply not needed. Bad roads and low engine power only permitted moderate driving speeds. Second,the approach of directly transplanting (with almost no change) shapes which had been developed for aeronautical and marine purposes was not appropriate[1]. The shape of cars changed in an evolutionary manner over the years in order to improve the efficiency.
