Abstract

The time-averaged, Navier-Stokes equations are solved numerically by a finite-volume method and applied to study flow around two-dimensional car like body. The finite volume equations are formulated in strong conservative form on a general, non-orthogonal grid system. The resulting equations are then solved by an implicit, time marching, pressure-correction based algorithm. The steady state solution is obtained by taking sufficient time steps until the flow field does not change with time. Numerical predictions are obtained with the standard k-ε turbulence model and with the extended k-ε model. Both models were able to predict the major, experimentally observed, flow characteristics including the small separation bubble near the rear end of the body. However, the extended k-ε model predicted a longer wake region than the one obtained with the standard k-ε model.
