Abstract

A three-dimensional vortex method for gas-particle two-phase compound round jet is proposed. The method simultaneously calculates the behavior of the vortex elements, discretizing the gas flow field, and the particle motion through the Lagrangian approach. The two-way coupling is based on that for the two-dimensional vortex method presented by one of the authors in a prior paper. To discuss the validity and applicability of the method, an air-particle two-phase jet issuing into the co-flowing air is simulated. It is confirmed that the change in the air turbulent features due to the loaded particles is parallel with the existing measured and simulated results.
