NUMERICAL SIMULATION OFTHE LAG RANG IAN BEHAVIOR OF SOLID PARTICLES IN IMPINGING LIQUID JETS

Abstract

Lagrangian behaviors of solid particles released in an axisymmetric submerged water jet impinging onto a horizontal plane surface have been studied numerically. The impinging jet flow (Re = 13,000) is represented using a modified k−ε turbulence model proposed by Kato and Launder (1993). Trajectories and velocities of the particles are calculated using a one-way coupling Lagrangian eddy-particle interaction model based on Schuen et al. (1983). The assumption of isotropy of local fluid velocity derivatives is made to model the added mass term and the pressure gradient term in the particle equation of motion. Thousands of glass particles (particle to fluid density ratio, ρpf = 2.6) of 1.05 mm diameter are released at the exit of the jet. The mean and root mean square (RMS) velocities of particles simulated are in good agreement with experimental data obtained with a stereoscopic particle tracking technique.
