摘要: Previous study of authors showed that kappa-taf turbulence model has a good accuracy for prediction hydrodynamic behaviour near wall in gas-solid boundary layer flow. In two-phase was derived from Yokomine et al. modified kappa-epsilon model. the present study, new version two phase been presented. this we use Adeniji et.al. modifications to account effect solid particles both on kinetic energy and it's dissipation rate. The compared with later flow region layer. governing equations Eulerin-Eulerian approach by different models have solved numerically using finite volume method. comparison available experimental data, obtained results kappa-taf, based modifications, better agreement than
