Application of phase change material-based thermal capacitor in double tube heat exchanger�A numerical investigation

In many heat transfer related applications, there is a need for a stable, constant supply temperature. As a result, the integration of intermittent renewable sources of heat into these processes can prove to be challenging, requiring special temperature smoothing devices or strategies. This study fo...
