TURBULENCE CLOSURE MODELING OF THE DILUTE GAS-PARTICLE AXISYMMETRIC JET.

A turbulence closure model has been developed for calculating dilute gas-particle flows. The model is based on a standard turbulence model which has been modified to account for the added dissipative effects caused by the particles. The fluid and particulate phases are treated as separate, interpenetrating continua and separate governing equations are solved for the mean velocity of each phase. This permits the slip between the phases to be computed. The model is used to compute the gas particle axisymmetric jet in the developing region and good agreement is obtained between the calculated mean and tubulent fields and the available experimental data.
