As for the fluid problems of MEMS (Micro Electro Mechanical Systems) such as micro-inkjets and micro-pumps, there are many cases of incompressible and compressible flow problems. In this paper, orthogonal basis bubble function finite element method is proposed for compressible viscous flow. As for the numerical examples, analyses of flow in a micro-pump are investigated with respect to the numerical accuracy and stability of orthogonal basis bubble function element stabilization method. By applying our scheme to compressible flow problems in micro-pumps under some collaboration with experimental researchers, it is confirmed that our method is very powerful in the micro scale simulations.
