Strujanje gasova u mikro-kanalima pri malim vrednostima mahovog broja, korišćenjem graničnih uslova klizanja višeg reda
Low mach number, high order rarefied gas flow in micro-channels
Abstract
U radu se tretira izotermsko strujanje razređenog gasa u mikro-kanalima promenljivog poprečnog preseka. Pretpostavlja se da je odnos kvadrata Mahovog broja i Rejnoldsovog broja mali, tako da se inercioni članovi u osnovnim jednačinama mogu zanemariti, a uticaj viskoznosti je dominantan u celom preseku kanala. Koriste se granični uslovi klizanja gasa na zidu višeg reda i pokazuje da razređenost gasa dovodi do povećanja masenog protoka pri istom odnosu ulaznog i izlaznog pritiska.
Isothermal rarefied gas flow in micro-channels of slowly varying cross section is treated in this paper. It is assumed that the ratio of the reference Mach number square and the reference Reynolds number is a small quantity, so that inertia can be neglected and the effect of viscosity is spread over the whole cross-section of the channel. Higher order slip boundary condition on the wall is used for the solution of governing equations. Gas rarefaction leads to increase of mass flow rate for the same inlet and outlet pressure ratio.
