Compared with the others, this model is distinguishes by an extended system of nonequilibrium chemical reactions while taking into account the multiphase non-equilibrium. Lagrangian particle methodology was used. The particle phase change is simulated kinetically and included two solid Al2O3 crystalline structures: meta stable gamma and stable alpha forms. The simulation results were compared with the available results of the other authors. There was a satisfactory agreement regarding the results of the main gaseous component concentrations. Comparison of the simulation results with experimental data also showed their satisfactory agreement.7 pagesPDFenUniversity of PretoriaCompressible multiphase supersonic jetsNon-equilibrium physical and chemical processesNonequilibrium chemical reactionsLagrangian particle methodologyAl2O3 crystalline structureMeta stable gammaStable alpha formGaseous component concentrationsPresentation
