Abstract

A fundamental study to investigate the effect of pulsatile flow past square cylinder at Reynolds Number, Re = 100 and Prandtl Number, Pr = 0.7 has been performed. The flow pattern is represented by three different non-dimensional parameters: the Richardson number (Ri), amplitude (A) of the incoming pulsatile flow velocity, and Keulegan-Carpenter number (Kc = Vo/Lω). The equations solved are Navier–Stokes and energy equation to compute the dynamic flow field. The numerical simulations are implemented by using commercial a finite volume solver. The parameters varied are Ri, (0, 0.1 and 0.25), A (0.2, 0.4 and 0.6) while Kc is kept fixed at 0.5. The effect of pulsatile flow is studied and results are compared with previous numerical results for uniform flow. It is found that for the case of Pulsatile flow vortex shedding continues even for Ri = 0.25. Also the number of Vortices formed and the distance traveled by said vortices is determined by the oscillating wave amplitude .
