Simulation de l'écoulement autour de deux cylindres en tandem

Abstract: Flow simulations over two circular cylinders in tandem are carried out at a Reynolds number of 100, using a fully coupled resolution method for solving the two-dimensional Navier–Stokes equations. A critical cylinder spacing was found between 3.95 and 4.0 cylinder diameters. The fluctuating forces jumped appreciably at this critical gap, like the shedding frequency and the mean drag.
