CALCULATION PROCEDURE FOR TWO-DIMENSIONAL PARABOLIC TWO-PHASE FLOWS USING INDEPENDENT COMPUTATIONAL GRIDS FOR EACH PHASE.

A computational marching procedure for two-phase flows which are dispersed, parabolic, and turbulent is outlined in detail. Convection, diffusion and viscous action as well as entrainment and volume fraction fluctuations are taken into account for both phases. Each phase is calculated in its own grid to reduce false diffusion to a minimum. The use of two independent grids requires formulae for the transfer of variables which are presented. A test case is examined to estimate the effect of false diffusion on the second phase. A two-phase jet is calculated and the results are found to be in good agreement with experimental data.
