Özet:

In this thesis study, Ahmed Body and MIRA Notchback model were investigated experimentally. The drag coefficients of reference models were measured at three different Reynolds number via balance technique. The wakes of reference models were also investigated and the suitable location in order to measure the drag coefficient was determined via momentum integral method. Surface pressure of two different types of vehicle models was measured at three different Reynolds number. The wakes of Ahmed Body which has blunter shapes and sharp edges and MIRA Notchback model were investigated qualitatively by using laser and smoke and photographed. As a conclusion, it was investigated that for Ahmed Body model the drag coefficient increased as the Reynolds number increases, for MIRA Notchback model the drag coefficient decreased while the Reynolds number increases within the investigated limits.
