Numerical method for threedimensional unsteady incompressible NavierStokes equations
Abstract
Computations of unsteady incompressible flows are carried out using the threedimensional unsteady NavierStokes equations. Direct integration of equations is achieved by a finite difference method in a generalized coordinate system. The pressure equation is solved by minimizing a discrete norm of the velocity divergence. The method is applied to study the flow around an impulsively started circular cylinder.
