Experimental investigations on thermal energy storage system using nanoparticles enhanced phase change materials

Abstract

Renewable energy sources such as wind hydro solar etc play a vital role in the engineering field When compared with other energy sources solar energy has significant advantages as more efficient in the heating process low area consumption and cost effective The major problem with solar energy is a time dependent energy source with seasonal in the pattern Thermal Energy Storage TES system used to store the thermal energy for a considerable period and to utilize the thermal energy when the need arises The focus of this research is the storage of thermal energy and its effectiveness of latent heat dispersion on energy storage using Phase Change Materials PCM with modified thermal stratifiers on charging inlet of the tank The present work delivers a novel concept with swirl flow injection by enhancing the steady state thermal flow over the PCM material and it increases the charging efficiency of the TES system An inlet charging fluid sprayed on every spherical capsule entirely through the centrifugal motion of the governor nozzle via swirl flow in the form of Heat Transfer Fluid HTF flow line with the helical pattern This centrifugal force also known as inertial force which directs the water flow away from the axis of rotation newline
