Abstract
This paper describes a transient model of a loop heat pipe (LHP) based on a mass-spring-damper system, and its verification with an experimental result. The model is based on the one-dimensional and time dependent conservation equations. The momentum equation and energy equation were solved in the model. Mass-spring-damper system was also solved to calculate the two-phase length. The calculation results were compared with the experimental results of a LHP with PTFE wick and ethanol as a working fluid. The calculated result had the good agreement with the experimental result.
