Abstract

The prolate spheroid is geometrically very simple but the flow characteristics are complex which are dominated by transition and three-dimensional separation phenomenon having both primary and secondary vortex. The transition phenomenon in this flow is triggered due to the stream wise Tollmien-Schlichting (T-S) wake instability and cross flow instability, which makes the prediction more challenging due to lack of effective predictive tool to model transition. The present work aims at simulating numerically the three-dimensional turbulent flow past 6:1 prolate spheroid at Re=4.2 x 106 using RANS approach for which experimental data are available in literature. These simulations have been carried out using parallel version of the in-house multiblock structured incompressible flow solution code 3D-PURLES (3D Pressure based Unsteady Reynolds Average Navier Stokes and LES solver).
