3D model of flow in micro channels

Abstract

The micro channels are important components in many micro - electro - mechanical systems (MEMS) and technical systems. They are used to transport a gas or a liquid into devices and the systems. In our work, the gas flows into a micro channel have been studied for various shapes and sizes of the micro channels. Numerical simulations of compressible flows through a micro channel are performed by solving the Navier–Stokes equations and the quasigasdynamic equations (QGD). The numerical approaches are realized on hybrid parallel computer systems. The software includes the Domain Decomposition technique, the Message Passing Interface (MPI) for organization of interprocess data exchange and an application programming interface Open Multi-Processing (OpenMP). The calculations are performed on the Heterogeneous Computer Systems with Video Processing Units (VPU) and the classical microprocessors - Central Processing Unit (CPU).
