Simulation of high-speed nonequilibrium heterogeneous turbulent flows with phase transition

In this paper the method of modelling of high-speed nonequilibrium two-phase turbulent flows with phase transition in disperse phase is presented. The method proposed in this paper has the following features: 1) the mathematical model includes conservation equations for gas and solid particles, as well as the equations for gas vibration molecular energy, conservation of species and phase transition equation for particles; 2) the equations for the particles are solved mixed Euler-Lagrange formulation; 3) the solver algorithm is two-way coupled; 4) a special turbulence model taking into account the effect of flow compressibility is implemented. The main case considered in this paper is crystallization process of aluminium oxide Al2O3 particles in underexpanded jet flow with cross-flow at different angles of attack. Simulation results for jets of different configuration are presented.
