The objectives of this paper are To show that the application of the thin thermal boundary layer approximation to collapsing bubbles is incorrect although this approximation has been used by all investigators interested in cavitation. To show that the available analyses based on the heat balance integral method contain a significant error because the assumed temperature profiles are incorrect when applied to a spherically symmetric problem. To solve the spherically symmetric phase change, i.c. moving boundary, problem by means of the heat balance integral method using the appropriate temperature profile. To use the results in an analysis of diffusion controlled bubble growth and collapse. Two solutions of the phase change problem are presented. Author
