Therefore, it has to be included inside erivatives of the transport governing equations. nce equations are obtained by formal integration volumes surrounding each grid node. Up-wind s used to insure that the influence coefficients are ve to reflect the real effect of neighboring nodes l central node. Finite-difference equations are ively, for U, V, p’ ( pressure correction), enthalpy ass fractions, utilizing a grid of (60X40) nodes. nodes in the axial direction are needed to resolve tructure of the thin reaction zone inside the porous porous burner uses a premixed CH4-air mixture, iating characteristics are computed numerically, lux radiation model.
