Eulerian–Eulerian RSTM-PDF Modeling of Turbulent Particulate Flow

A novel 3D computational model was developed for the turbulent particulate two-phase flow simulation in rectangular channel. The is based on Eulerian approach applied to Reynolds-averaged Navier–Stokes modeling and statistical Probability Distribution Function method. uniqueness of method lies direct calculation normal transverse components Reynolds stresses both gas particles. Two cases were examined: a conventional channel grid-generated turbulence flow. obtained numerical results have been verified validated by experimental data, received from particle dispersion test. computed values particles’ maximum value concentration distribution show good agreement with results. examples are ranged coal other bulk material pneumatic transport, vertical fluidized beds, gasifiers, chemical reactors.
