Abstract
Two dimensional particle-laden turbulent gas jets impinging on a flat surface are studied numerically in erosion experiment. Two-phase model for dilute particle-fluid systems with a large pure phase-density ratio is considered. Lagrangian approach is used to both phases in one-way coupling conditions (motion of the particle phase does not affect the motion of the fluid phase). Random vortex method is applied to resolve the turbulent flow in the fluid phase. The impact particle speeds, incidence angles, and particle surface densities are predicted from the particle equation of motion. Using a cutting wear model for ductile materials, the relative erosion rate along the impinged surface is estimated. The whole process is simulated and visualized by tracing the motion of the fluid and solid particles, and plotting the graph of the predicted erosion.
