NON - CONDENSABLE GASES AN D OSCILLATING HEAT P IPE OPERATION

The Oscillating Heat Pipe (OHP) is a novel, wickless heat pipe that relies on the phase change induced motion of a contained working fluid to transport heat between the evaporator and condenser. This paper investigates the effects of non-condensable gas (NCG) on OHP operation. A brief synopsis of the existing literature is presented before discussing the experimental setup, method, results, and conclusion. This paper clearly shows that: 1) NCG injection into an OHP produces an overall rise in the steady-state operating temperature, pressure, and thermal resistance; 2) Like LHPs OHPs are more tolerant of NCG than conventional heat pipes.
