AbstractTransient motions of a vapor around its two spherical condensed phases caused by the interaction with a shock wave have been considered numerically based on the fluid dynamic formulation, i.e., the compressible Navier-Stokes equations subject to the boundary conditions appropriate for phase-change processes involved which have been derived earlier from the kinetic theory analysis. Forces acting on the spherical condensed phases and the mass flows onto them are calculated and are compared to the corresponding quantities not only for the single sphere case but also for the solid two-sphere case. The effects of the phase change processes occurring on the peak values of the transient forces acting on the spheres may be grasped. The thrust force, which may appear in the solid two-sphere case, is likely to be suppressed in the present case with phase change processes involved.
