Thermo-fluid dynamics of Loop Heat Pipe operation

The paper presents a thermo-fluid dynamic model for the transient operations of a Loop Heat Pipe. The Fourier heat conduction equation in a hollow cylinder is solved to determine the temperature distribution of the compensation chamber and the cavity. A one-dimensional transient model is also derived for the vapor temperature in the condenser section of the Loop Heat Pipe. The thermo-fluid dynamic characteristic of a Stainless Steel/Ammonia Loop Heat Pipe is analyzed.
