主 题：Cavitating flow cavitation model verification and validation(V&V) error estimate
摘 要：The present paper investigates the turbulent cavitating flow around the Clark-Y hydrofoil with special emphasis on the influence of cavitation models by verification and validation(V&V)*** solver coupled with the three major cavitation models(i.e.,Zwart-Gerber-Belamri,Schnerr and Sauer and full cavitation model,which are abbreviated to ZGB model,SS model and FC model respectively)is employed in this *** results indicate that the three cavitation models can properly reproduce the cavitation *** model and SS model give better prediction in the overall cavitation *** model exhibits an obvious under-estimation for the sheet cavity,and the predicted volume fraction is closely related to the turbulent *** verification and validation procedure is involved to quantitatively assess the accuracy of these three cavitation *** is indicated that the V&V procedure is suitable for the unsteady cavitating *** errors estimate is robust and conservative within the cavitation region,while gets closer to zero in the no-cavitation *** addition,ZGB model exhibits the highest overall accuracy among the three models,which further verifies its wide applicability.
