内容記述 | The some analysis on the suspension flow with solid particles cannot use the Boussinewq approximation for the case that the density of solid particles is appreciably larger than the density of ambient fluid. The formulation of k-\epsilon\ turbulence model for the solid-fluid two phase flow, in which the flow is treated as the non-Boussinesq fluid. , is represented. The basic equations consists of the continuity equation, the mass conservative equation for the solid phase, the Reynolds equation, the equation of kinetic energy of turbulence (k) and the equation of the viscous dissipation rate (\epsilon\) in which k- and \epsilon\-equations are corrected. The model calculations for the snow drift on the horizontal plane and in the case of the slope angle of 30 \deg\ are carried out. In the case of the horizontal plane, as the bed concentration of snow particles is larger, the velocity is slightly larger. In the case of \theta\=30\deg\, the velocity becomes remarkably large as the increase of the bed concentration. Comparing the results of the calculation using the Boussinesq approximation and the calculation assuming the non-Boussinesq fluid, the critical bed concentration for both case is found out to be 0.03%. | |||||
