Numerical simulation to evaluate heat transport in forced oscillated system

Abstract

In this study, focusing on the sensible heat transport of the main heat transport in OHP, we compared the relationship between heat transport and liquid position using a model using numerical simulation based on particle method. By comparing with heat transport by dream pipe effect, we showed propriety of this analysis method. Moreover, the heat transfer was evaluated when the amplitude of the wall oscillation was large and frequency is small. As a result, we showed that the heat transport amount increases by increasing the frequency, but the increasing rate decreased by increasing the frequency. In other words, it is considered that there is a peak structure in the temporal change of the heat transport amount. It was also found that the amount of heat transport changes depending on the difference in the initial position of the system. It is considered that the influence on the heat flowing in the system is different for initial position of the liquid.
