FOURIER PSEUDOSPECTRAL-FINITE DIFFERENCE METHOD FOR INCOMPRESSIBLE FLOW被引量:1
《Journal of Computational Mathematics》1994年第4期312-329,共18页Guo Ben-yu  Xiong Yue-shan(Shanghai University of Science and Technology, Shanghai, China ) 
A Fourier pseudospectral-finite difference scheme is proposed for unsteady Navier-Stokes equation. It is showed that the numerical solution keeps semi-discrete conservation. The strict error estimation is established....
