文摘In this paper the extensive calibration procedure of a hybrid model for predicting cavitation inception in free shear layers described.The hybrid model treats the cavitation process as two decoupled processes,a hydrodynamic one and a bubble dynamic one.The hydrodynamic part is modeled by a small-scale physical model,whereas the bubble dynamic part is solved mathematically.Besides a short explanation of the hybrid model,the procedure of fixing the free parameters of the mathematical formulation by given(measured)data from diverse test facilities is explained.
