| Abstract |
The thermal performance characteristics of gas-loaded heat pipe (GLHP) were investigated by using transient diffuse-front model. Numerical evaluation of the GLHP is made with water as a working fluid and Nitrogen as control gas in the stainless steel tube. The transient vapor temperature and wall temperature were obtained. It is found that the temperature profiles and gas mole fraction distribution have been mainly influenced by the diffusion between working fluid and noncondensable control gas in the condenser of GLHP. It is also found that the large power input make the diffusion region smaller. |
