| Research Abstract |
The effect of small solid particles on the performance of pulsating heat pipes (PHPs) was investigated using a 12 turn PHP made of copper tubes. Alumina, copper or silver particles were added into the working fluid, water, ethanol or R141b, and the enhancement of heat transport performance by small particles was clarified in detail. In addition, the mechanism of PHP was investigated by a visualization experiment and analysis on the oscillation of a liquid column in a square straight channel.
