Authors Abstract
Content
Reynolds Averaged Navier-Stokes equations (RANS) were solved for three cases, namely, flow over a half cylinder in a uniform stream, near a stationary wall and near a moving wall. Time accurate, incompressible computations were performed for a Reynolds number of half-a-million. Computed time histories of force coefficients exhibit a strong tonal nature representative of regular periodic shedding. The effect of the ground on the periodic shedding was studied and the computational results were compared with experiments for the free stream and stationary wall cases. Strouhal number computed from the computational simulations agrees well with the experimental results. Time averaged pressure distribution on the body and wall show reasonable agreement with experimental data.
