Short Description
Short description: Micro mechanical devices are rapidly emerging technology, where new potential applications are continuously being found. A simulation of internal and external gas flows in or aroundthese devices is important for their design. The flow motions described on the basis of the Navier-Stokes-Fourier compressible equations with diffusion coefficients determined by the first approximation of the Chapman-Enskog theory for the low Knudsen numbers.The gas flows are characterized with areas of low speed flows (low Reynolds numbers). The flows can go from high speed supersonic to very low speed regimes down to the incompressible limit. This made the pressure based numerical methods very suitable to be used for calculation of this kind of gas flows. The finite volume method SIMPLE-TS (a modification of SIMPLE created by K. S. Shterev and S. K. Stefanov) is used.
Problems Solved
Steady and unsteady flow past square in a microchannel
