摘要
A "dual time" method for the solution of unsteady three dimensional Navier Stocks equations is described in this paper. An implicit real time discretisation is used, and then the equations are integrated in a fictitious pseudo time. When marching in a pseudo time, the finite volume method, multi grid scheme and other acceleration techniques used in steady flow calculations can be used. Balwin Lomax turbulence model is applied to simulate the turbulence.
