Abstract
A flow analysis for the erosion-corrosion damaged automotive water pump which causes vehicle fire is numerically performed using the CFX program, computational fluid dynamics (CFD) code. The blade bending deformation and the blade clearance enlargement are considered in the analysis of performance reduction. For the cavitation analysis, the homogeneous multi phase model is adopted using the Ralyleigh-Plesset model for the rate equation controlling vapor generation and condensation.
