Experimental and numerical study on the effect of multiple phase change materials thermal energy storage system

Nowadays, thermal energy storage using Phase Change Materials (PCMs) receives a great interest due to its high density especially for low and medium temperature applications. Nevertheless, PCM suffers from the conductivity during charging discharging of heat. In this study, multiple technique has been investigated as enhancement in shell-and-tube heat exchanger. The investigations have conducted experimentally numerically different arrangements working conditions Paraffin wax. experimental work shows higher average arrangement than other two arrangement. numerical analysis focuses on geometrical parametric study by varying both radial axial dimensions cylindrical storages. results show that longer enhances melting time compared wider same amount PCM.
