Heat Transfer Enhancement in a Paraffin Wax Thermal Storage System
TL;DR: In this paper, a thermal storage system consisting of vertically arranged fins between a heated and cooled horizontal finned-tube arrangement is reported, where the high thermal expansion coefficient and low viscosity of paraffin wax, at temperatures above 50/sup 0/C, are utilized to induce natural convection in the liquid phase even at small thicknesses.
Enhanced heat conduction in phase-change thermal energy storage devices
TL;DR: In this paper, a simplified numerical model based on a quasi-linear, transient, thin fin equation was proposed to predict the fraction of melted phase change materials and the shape of the liquid-solid interface as a function of time with sufficient accuracy for engineering purposes.
