Integral formulation of a diffusive-convective transport equation for reacting flowsSamec, Niko (Avtor) Škerget, Leopold (Avtor) fluid mechanicsboundary element methoddiffusionconvectiontransport problemsreacting flowThis peper deals with a numerical solution of a diffusive-convective transport equation for reacting flows based on boundary domain integral formulation for diffusive-convective fundamental solution. A great part of attention has been dedicated to the numerical treatment of the diffusive-convective transport equation for high Pe number and reaction term values as the convective or reaction term becomes dominant compared to the diffusion one. In this case, the hyperbolic character predominates the ellipticity or parabolicity of the governing transport equation, and stability problems arise in the numerical solution. Numerical efficiency of the developed numerical implementation is tested against analytical and numerical results for the typical test cases of diffusive-convective transport problems (i.e. multicomponent reacting flows).20042012-06-01 11:35:25Neznano27524UDK: 536.25:532.72COBISS_ID: 8913430ISSN pri članku: 0955-7997NUK URN: URN:SI:UM:DK:CUZDV9SDsl
