Modeling of Boiling Heat Transfer System and Chaos in Microchannel

Abstract:

A model of boiling heat transfer system was established by introducing disjoining pressure produced by three phase molecular interactions and Lie algebra analysis for a developed bubble in micro channel and simulation of chaotic movement of the obtained interface dynamic system was carried out in this paper. Experiments for 0.6 mm2 mm rectangular micro channel were carried out to obtain the pressure time serials. Power spectrum density analysis for this serials shows that the system is in chaotic state if the frequency is above 7.39Hz.The result indicates that high heat transfer performance of micro channel phase change system may relate to the characteristics of chaos.
