Abstract:Similar to an electric diode, thermal diode transmits heat in a specific direction, and thermal rectification is also a fundamental phenomenon for active heat flow control. However, in practical applications, thermal rectification will need to be operated under transient conditions. In this study, transient thermal rectification ratio of a one dimensional heterostructure is numerically investigated using the finite element method. Effect of interface thermal resistance, interface initial gap, periodic boundary… Show more
