Simulation of Heat Transfer Characteristics of Sensible Heat Storage System

Abstract

The aim of present work includes development of a numerical model for the prediction of heat transfer characteristics of a sensible heat storage system (SHSS) followed by the validation using a small scale experiment. The concrete structures with entrenched steel pipe with definite maximum energy storage capacity was considered for the modelling and in an experimental scheme. The charging-discharging time, temperature profiles were predicted with significant accuracy by the developed model. The dependence of sensible heat storage performance on operating temperature range, thermo-physical properties of sensible heat storage material, and heat transfer fluid is also established. The excellent agreement between experimental and simulation results ensured the applicability of develop ed models for higher temperature full-scale applications.
