Numerical simulation of pulsating flow around a cube C. Dargent, D. Dartus, J. George Institut de Mecanique des Fluides de Toulouse, Avenue du Professeur Camille Soula, 31400 Toulouse, France ABSTRACT The purpose of this paper is to present numerical solutions for two-dimensional time dependent flow around a cube. A computational analysis is carried out using the commercially available fluid dynamics code PHOENICS for a solution of the Reynolds equation, the continuity equation and, for the turbulent closure, the classical k-e model is implemented. The variant parameter is the angle of attack that varies sinusoidally in time between 10 and 30 degrees. Thus, the inflow conditions and the boundary conditions vary in time in the same manner. We show the wake characteristics for the two mean velocity components and for some inflow conditions, the occurrence of vortex shedding. INTRODUCTION The study of oscillatory flow past bodies is very important to predict the forces induce
