Calculation of unsteady flows around a cylinder by solution of the incompressible NavierStokes equations
Abstract
The twodimensional unsteady viscous flow around a circular cylinder has been studied by direct solution of a velocitypressure formulation of the NavierStokes equations. The equations include such boundary and initial conditions as profile adherence, uniform flow to infinity, and zero initial velocity. A discretization in space is performed using a finite difference scheme, and a discretization in time is performed using AdamsBashforth/Euler schemes (Dang and Morchoisne, 1989). An implicit residual smoothing technique is introduced to make the scheme unconditionally stable.
