Numerical Simulation of Liquid-Solid Two-Phase Flow Reflux in Particle Impact Drilling System

Abstract:

In particle impact drilling system, the steel particles would be recycled for economic reason. Thus, whether particles can return to the ground under certain conditions is an important problem. In this paper, the relationship between critical flow rate and annular gap is numerically studied using the Eulerian multiphase model in FLUENT software. Both the numerical and the experiment results show that the critical flow rate decreases with the increasing annular gap, and the simulation results correspond well with experimental results.
