Numerical simulation of heat transfer in nucleate pool boiling

A mathematical model was proposed to describe the heat transfer in nucleate pool boiling. The model addressed the three-dimensional conduction heat transfer process within the problem domain comprised of the heating wall, and the effect of bubbles or sites was represented through boundary conditions. Numerical simulations were performed and an excellent agreement between the available experiment data and numerical simulating results were gained. By numerical simulation, the predicting methods of the bubble influence area factor and the flow strength parameter were obtained. In addition, the nonlinear characteristics of wall temperature variation and bubble wait time were identified.
