A New Conservative Phase Change Model for Nucleate Boiling
نویسندگان
چکیده
A new mass-conservative phase change model has been developed for the nucleate boiling simulation. The conservative CIP scheme is used for surface tracking in order to satisfy the mass conservation exactly. As the phase change model, a sharp-interface model is developed, in which the phase change rate can be computed from the heat flux to the interface in a straightforward manner. The developed numerical method is verified for one dimensional phase change problem, and three dimensional bubble growth problem in superheated liquid in unbounded domain. Following these verifications, a saturated nucleate pool boiling simulation is conducted, using a micro region model which can treat the micro physics close to the wall.
