For that purpose boundary layer can be modified by perforated plates with holes of specific sizes. The questions which rise in such configuration are related to the existence of optimal size of the holes and the influence of microscale phenomena on the global flow patterns. This paper concentrates on the issue of the entrance effects on the microchannel flow. It is shown that mass flow rate is only insignificantly influenced by slip effects. Global parameters such as pressure difference and geometrical shape in more pronounced way alter flow behavior. In this paper we concentrate on the numerical investigation of the microchannel flow for Kn < 0.01 and Re < 500. The channel length is finite. Hence, entrance and outlet effects on microchannel flow can be studied. Słowa kluczowe: perforated plates, microchannels, gas flow simulations Afiliacje autorów:
