The numerical analyses are performed to investigate the effects of an electric field onthe growth and departure of a bubble attached to a heating surface. The bubble growthprocess is considered to be controlled by the unsteady heat transfer between the liquid andgas bubble. During the bubble growth, unsteady solutions on the equilibrium bubble shape inan electric field are obtained by solving the free boundary problem without any approximationto the bubble shape. The free boundary problem consists of the governing equations forelectric field and temperature field and the normal stress condition at the bubble surface.The numerically generated orthogonal grid system is employed for a finite-difference solutionof the free boundary problem. The bubble departure time and volume are also determinedfrom the force balance on the bubble under the electric field
