Enhancing the heat transfer performance of compact heat exchangers by minimizing the contact resistance between fins and tubes
Thermal contact resistance or, its reciprocal, thermal contact conductance is an important parameter in a wide range of thermal phenomena. It plays a significant role in heat transfer applications such as electronic packaging and nuclear reactors. This parameter also appears in fin-tube heat …
