On simulations of strong evaporation flows of a vapor from its plane condensed phase with finite thermal conductivity -Method of application of the Fluid Dynamic Formulation as the governing system-
Fluid Dynamic Formulation
Condensed phases with internal structure
Flow problems associated with phase change processes even if they are within the range of the continuum limit have to be dealt with based on the kinetic equations because the nonequilibrium nature of the Knudsen layer, which is always existent in the close vicinity of the interface, is the cause for the phase-change processes to occur at the interface. Recently, a new governing system of equations has been proposed by Onishi et. al. to deal with at the ordinary fluid dynamic level various flow problems, transient to steady, due to phase change processes. This new system, called the Fluid Dynamic Formulation, can be used as the substitute of the kinetic equations for the analyses of flow problems of such kind. However, the method of application of this new governing system is not so straightforwad as is expected. The present paper will show 1) how to use the Fluid Dynamic Formulation as the governing system of equations in place of the kinetic system by taking up simple one-dimensional problems and 2) the approriateness of the results obtained by comparison with the corresponding results obtained based on the kinetic system.
