FLOW OF A METHANE VAPOR–DROP MIXTURE IN A CHANNEL OF VARIABLE CROSS SECTION

Results of numerical investigation of the dynamics of a methane vapor–drop mixture in a channel of variable cross section are presented. Calculations were performed on the basis of a one-velocity, one-temperature model in the diffusion approximation with the use of the scheme of a nonequilibrium phase transition. A computational method was verified by comparison of the results of calculations of the dynamics of a water vapor flow with experimental data. The temperature fields and the partial density of the condensate in a Laval nozzle were determined depending on the temperature of the flow at the input of the channel and on the pressure drop in it.
