A non-staggered pressure correction numerical method has been developed to calculate both incompressible and compressible flows at all speeds. The pressure oscillation is solved by a special treatment of pressure interpolation on collocated grids, with all variables being located at the center of the control volume. Both convection and diffusion terms of the governing equations are discretized with the second-order central differencing scheme. The method is verified on a number of test cases, and the results compare favourably with other numerical results.
