TL;DR: In this article, the authors performed experiments on a pulsating heat pipe (PHP) consisting of a heating section, an adiabatic section, and a condensation section incorporating a heat sink.
Abstract: Experimental studies were performed on a pulsating heat pipe (PHP), consisting of a heating section, an adiabatic section, and a condensation section incorporating a heat sink. The capillary tube used in this study has an inside diameter of 1.18 mm and a wall thickness of 0.41 mm. The experiments were conducted under the condition of pure natural convection, for heating powers from 5 to 60 W, fill ratios from 60% to 90%. Three working fluids—FC-72, ethanol, and deionized water—were used. The thermal oscillation of the thin wall surface was recorded by a high-speed data acquisition system. Such thermal oscillation waves are random for some run cases due to the randomly distributed vapor plug and liquid slugs inside the PHP. The thermal oscillation amplitude is much smaller for FC-72, due to its lower surface tension, than for ethanol and water, while the oscillation cycle period for FC-72 is shorter than for the other two fluids, indicating the faster oscillation movement in the channels, possibly due to t...

TL;DR: In this paper, a two-dimensional heat pipe transient analysis model, called HPTAM, is developed for simulating operations of fully-thawed heat pipes, where the axial distributions of liquid and vapor pressures, effective radius of curvature of the liquid meniscus at the liquid-vapor interface, and liquid pooling and recession following step function heatup and cooldown transients of a horizontal water heat pipe.

TL;DR: In this article, a complete mathematical model for transient two-dimensional heat pipes is presented and the numerical results for both simulated compressible vapor flow with high Mach numbers and the vapor flow of a high-temperature heat pipe are compared with the experimental data in the literature.
Abstract: A complete mathematical model for transient two-dimensional heat pipes is presented. The numerical results for both simulated compressible vapor flow with high Mach numbers and the vapor flow of a high-temperature heat pipe are compared with the experimental data in the literature. The transient responses of heat pipes to a pulsed heat input are also investigated. It is very important to include the porous wick and the wall in the numerical calculations for the transient analysis of heat pipes and to treat the entire heat pipe as a single system rather than to analyze the vapor flow alone.
