Numerical Simulation of Flow Interference Between Two CircularCylinders
Viscous flow past two circular cylinders in tandem and side-by-side arrangements is investigated numerically. The solution to the Navier-Stokes equations is obtained by means of a cell-centred finite volume method (FVM) based on a structured Cartesian grid with collocated variable arrangement. The pressure-velocity coupling is evaluated by using the SIMPLE algorithm. The 2D Cartesian cut cell mesh is generated on the horizontal plane, which is extended vertically to form the 3D grid. The simulations are based on the Reynolds number of 200, and the gap between the two cylinders are 1.5.3D for side-by-side arrangement and 3.4D for tandem. Instantaneous velocity contours of the flow around the cylinders and time histories of force coefficients are presented.
