A three-dimensional particle method simulation analysis of jet impingement behavior was carried out to validate the results of the analysis for the erosion rate of metal plates obtained from previous experiments. The analysis reproduced the melt pool formation and crust formation behaviors that affect the erosion behavior of the plate, confirming the applicability of the present method.
