| Abstract: | With the development of J-T cryocooler, it is urgent to study the boiling mechanism of multicomponent mixed-refrigerant further. In this paper, it is firstly argued the difference between pure refrigerant and multicomponent mixed-refrigerant. Then, several mechanisms of pool nucleate boiling are introduced, and the reason of pool boiling coefficient decrease is pointed out. Finally, it is enumerated several common correlations of multicomponent mixed-refrigerant for pool nucleate boiling. |
