摘要
Abstract
The single bubble boiling process was simulated by means of the Level Set equation in the Comsol Multiphysics software,the microstructure network was established,boundary conditions were provide,and the mass,momentum,energy and Level Set equation were solved. The satisfied simulation results were acquired. The changes of the holdup,pressure field,velocity field and temperature field with time were studied. The influences of contact angle and wall effect on the bubble departure diameter and bubble growing period were investigated. It was showed that,when the contact angle was bigger than 12°,the bigger the contact angle,the bigger the departure diameter and the longer the bubble growing period. But the bubble departure diameter was constant when the contact angle was less than 12°. As the heating foil diameter was less than the bubble departure diameter,the bubble was not easy to grow up and leave the wall. When the heating foil diameter was more than the bubble departure diameter,the bubble departure diameter was constant and the bubble growing period decreased with the heating foil diameter increasing.关键词
