ENTROPY GENERATION ANALYSIS FOR A PULSATING HEAT PIPE
Get access
ABSTRAKT
The entropy generation is based on the second law of thermodynamics. In the present study, the entropy generation in a U-shaped Pulsating Heat Pipe (PHP) is investigated numerically. The following five parameters, which are vapor mass, liquid temperature, latent heat, sensible heat, and friction, determine the entropy generation. The results show that the entropy generation is significantly affected by the initial temperature in the PHP. Particularly, variation of the vapor mass is a primary factor of entropy generation. On the other hand, the amplitude of the entropy generation is barely related to the pressure loss at the bend in the PHP. However, the frequency of entropy generation with the pressure loss is faster than that without the loss of pressure at the bend.
