Abstract : In the present report the governing differential equations associated with a continuum theory of the motion of air-raindrop suspensions are solved to determine the dispersed-phase flow field for supersonic flow past a sphere. The equations are solved numerically by beginning at the forward stagnation line and marching downstream. Results of these calculations are displayed graphically and employed to illustrate interesting features of two-phase flows past blunt bodies. Also discussed are approximate analytical solutions valid for thin shock layers and the importance of nonnegligible dispersed-phase volume fractions and distributions of drop sizes within the dispersed phase.
