Abstract

A numerical simulation approach is discussed in regard to cavitational processes. A mathematical model is suggested to describe unsteady conjugate heat-mass transfer between a vapor-gas bubble and surrounding fluid. The model takes into account a spatial inhomogeneity of gas and fluid temperature fields as well as inhomogeneity of component concentration in the bubble.
