| Abstract: | In this paper, the program for solving viscous flow problems at all Mach numbers was developed based on the SIMPLEC algorithm, using the compressible form. It holds for not only compressible but also incompressible flow problems. Some typical compressible examples were calculated with the program, and the numerical results agreed well with the related literature and experimental data. Finally, the calculated velocity distribution at the orifice of the orifice pulse tube refrigerator was presented at the condition of the optimum opening of the orifice. |
