    Abstract: The purpose of this study is to experimental investigating of the hydrodynamics structure in a cylindrical stirred vessel generated by an eight concave blades turbine. Particle image velocimetry (PIV) system was used to evaluate the effect of the blade turbine in the flow fields. The flow is illuminated by a Nd: YAG 532 nm green pulsed laser source... Show More

    Abstract: Simplified vehicle has been applied in this paper to study the influence of wheel spoiler height on vehicle drag reduction. Two different conditions including stationary and rotating wheels were employed in numerical simulation with steady RANS (Reynolds Averaged Navier-Stokes) equations. Based on detailed analysis of flow around the wheels and int... Show More
