Strujanje disociranog gasa u graničnom sloju za slučaj porozne konture opstrujavanog tela
Dissociated gas flow in the boundary layer in the case of a porous contour of the body within fluid
Univerzitet u Kragujevcu, Mašinski fakultet
Sažetak
U radu se istražuje strujanje idealno disociranog gasa u graničnom sloju, pri čemu je kontura opstrujavanog tela porozna. Najpre je iz odgovarajućih polaznih jednačina graničnog sloja izvedena impulsna jednačina i uveden neophodni skup parametara poroznosti. Zatim su jednačine graničnog sloja razmatranog problema, pomoću svrsishodnih transformacija, dovedene na uopšteni oblik. Dobijene jednačine su numerički rešene u troparametarskom približenju. Za njihovo rešavanje je sastavljen neophodan program. Na bazi dobijenih rešenja izvedeni su zaključci o ponašanju pojedinih karakteristika graničnog sloja.
Abstract
This paper studies the ideally dissociated gas flow in the boundary layer when the contour of the body within fluid is porous. Firstly, the momentum equation has been obtained from the corresponding starting boundary layer equations and the necessary set of porosity parameters has been introduced. Then, the boundary layer equations of the considered problem have been brought to a generalized form by means of transformations. The obtained equations have been numerically solved in a three parametric approximation. A necessary program has been written to solve them. Based on the obtained solutions, conclusions concerning behavior of certain boundary layer characteristics have been drawn.
