NUMERICAL SIMULATION OF THE DYNAMICS OF MULTIPLE BUBBLE MERGER DURING POOL BOILING UNDER REDUCED GRAVITY
SINOPSIS
Numerical simulation of the growth and departure of multiple merging bubbles and associated heat transfer on a horizontal heated surface during pool boiling under low gravity conditions has been performed. A finite difference scheme is used to solve the equations governing mass, momentum and energy in the vapor liquid phases. The vapor-liquid interface is captured by level set method, which is modified to include the influence of phase change at the liquid-vapor interface. PF5060 is used as test liquid. The effects of reduced gravity condition and orientation of the cavities on the bubble diameter, interfacial structure, bubble merger time and departure time as well as local heat fluxes are studied.
