摘要

A transient overall model has been developed to predict the thermal and hydrodynamic behavior of a standard loop heat pipe. The model of the loop has been divided into subsystems, for which transient mass, energy, or momentum conservation laws have been developed. The comparison of the calculation and experimental results for a transient test allows one to validate the proposed model. Then, the model is used to study the development mechanisms of an oscillating behavior during the loop heat pipe operation. Two different patterns of temperature fluctuation have been highlighted by modifying the loop heat pipe external conditions (heat load, sink temperature, ambient heat exchange with the liquid line). The characteristics of these oscillations are then compared quantitatively to available experimental tests: these comparisons highlight the ability of the model to accurately predict the frequencies and amplitudes as well as how they are affected by the design and operational parameters.
