摘要
A model of the two-phase turbulent jet is presented. Consideration is given to cases in which the primary fluid phase contains a secondary phase of rigid particles. The mass fraction of the secondary phase is at most of order unity while its volume fraction is much less than unity. A set of model differential equations is developed for cases in which the mean velocities of the phases are sensibly equal. A first-order closure scheme for the axisymmetric jet is devised and the resulting equations solved numerically. This scheme accounts for momentum transfer between the phases and the imperfect response of the particles to the fluid turbulence. Satisfactory agreement with published experimental data is obtained for computed values of the mean velocity, and the mean mass flux of the particles. © 1979.
