Abstract

Latest vehicle development demands a solid background in aerodynamics to reduce the unsteady flow. The complexity implied in the vehicle conception especially due to the shaped and accessories that form its geometry creates the validation projects costly. The low speed flow field for a wedge-shaped and armoured vehicle model is investigated both experimentally and numerically. The wedge-shaped dimension is 100 mm X 100 mm X 49 mm which 28° wedge angle. In order to measure the velocity and flow characteristics, a wind tunnel study was performed with wind speed 5.18 m/s and validated using Computational Fluid Dynamics (CFD) simulation software ANSYS FLUENT. Details about the flow field, including velocity and flow pattern, are shown. Further CFD simulation of an armored vehicle model using the similar approaches was performed at speed of 22.2 m/s to predict the flow pattern.
