Abstract

Paraffin wax is an important material used in thermal energy storage (TES) systems. The thermal conductivity of the material is an important parameter that decides the degree of exploitation of the paraffin wax in TES systems. The thermal conductivity is improved by the addition of silicon oxide nanoparticles (1%, 2%, 4%, and 6%) to the paraffin wax. The average size of the SiO2 particles is equal to 38 nm. The addition of SiO2 nano-particles at very small ratios was found to enhance the thermal conductivity of the paraffin wax considerably. SiO2 nanoparticles, add to paraffin wax, have a significant effect in enhancing the thermal storage characteristics of paraffin Paraffin wax is an important material used in thermal energy storage (TES) systems.

Highlights

Ceramic nano-particles are potential candidates in the development of nanocomposites for many technological applications in mechanical, electric sciences, etc. [1,2,3,4,5,6]
The water will be eliminated from tissue by ascending alcohol strengths (75% to absolute), the tissue will be cleared in organic solvent like xylene, after that, the tissue will be placed in paraffin wax for a few hours, at that point it will be set in a mold with wax in order to cool and solidify; microtome will be used to cut the sections [16]
Silicon dioxide nano-powder was utilized to enhance the thermal conductivity of paraffin wax used for thermal energy storage applications

Summary

Introduction

Ceramic nano-particles are potential candidates in the development of nanocomposites for many technological applications in mechanical, electric sciences, etc. [1,2,3,4,5,6]. Polymer composites of nano-elements may exhibit thermal conductivity at low levels, low thermal conductivity portrays paraffin wax as other PCMS. This character limits the absorption and energy release rate. Thermal energy storage (TES) systems are systems that utilize a certain amount of material (like salt hydrates, paraffin, and organic compounds) to store thermal energy at low or high temperature regarding other systems. They are used to store the excess of energy to be utilized in later times and purposes [11,12]. The details of the measurements are described elsewhere [19]
