SIMULATION OF THE STRONGLY SWIRLING GAS-PARIICLE TURBULENT FLOW BY STOCHASTIC TRAJECTORY MODEL

The particle stocliastic trajectory model, integrating with a new version algebraic Reynolds stress model, was employed to numerically simulate the strongly swirling gas-particle turbulent flow in a iiovel vortex combustor(VC).The calculated distributions of theparticle density and tangential mass fiux agree with the measured test data。The simulationresults elucidate the following features of the VC gas-particle flow:peak values of the particle density occurring near the combustor outer wall,prolonged part...
