Mathematical model to predict heat transfer in transient condition of helical oscillating heat pipe

This research aims to study the heat transfer with a numerical model and experimental evaluation of a helical oscillating heat pipe (HOHP). Firstly, we created a numeric model of the HOHP to predict the time required to reach the steady state temperature and the heat transfer of the HOHP under transient conditions. Secondly, we measured the temperature at the pipe wall and evaluated the heat transfer rate from experiments and compared them with the numeric model. The results showed that the transient temperature and the heat transfer profiles of the HOHP from the numerical model were similar with the results measured from the experimental data. The results from numeric model predicted temperature profiles for attaining a steady state temperature were in close agreement, when compared to the numerical simulation of Boothaisong et al. (2015).
