A numerical method for bubble motion with phase change

A numerical method for computing the motion of bubbles undergoing liquid-va por phase change is presented. The method is based on a level set technique for capturing the phase interface, which is modified to include the effect of phase change at the interface as well as to achieve mass conservation d uring the whole calculation procedure. The modified level set method is app lied for numerical simulation of bubble rise and growth in a stationary liq uid. The numerical results are found to compare well with the data reported in the literature and the analytical solutions.
