Mass and momentum transport in a laminar isothermal two-phase round jet

Numerical predictions for a laminar axisymmetric gaseous jet seeded with solid particles have been obtained using a finite-difference solution procedure. The effects of interphase slip, Reynolds number, particle loading, particle size, and particle density are examined. The predictions are found to be in good agreement with available experimental data. Results indicate that the effectiveness of momentum transport K from the particles to the fluid is essential for correct flow prediction. The often assumed unity value of K leads to erroneous results.
