Phase relaxation model for 2phase flows
Abstract
A phaserelaxation model based on the Boltzmann equations for gasparticle mixtures is developed for twophase flows. It is shown that the computation of the basic model equations can be simplified by incorporating small intrinsic terms dependent on the densities of the gas and particle phases. The model is applied to the onedimensional steady propagation of shock waves in a gasparticle mixture, and the results are presented graphically. The importance of twophase flows in biology and astrophysics as well as for such engineering problems as chemical reactor design, petroleum transportation and recovery, dust explosions, pneumatic and hydraulic conveying, and powderedcoal combustion is indicated.
