• B231 Wall Temperature Fluctuation of Pulsating Heat Pipes

抄録

Heat transport characteristics of pulsating heat pipe were investigated by using 12 turn copper tubes with water as the working fluid. Wall temperature fluctuations were measured at 15 points on adjacent 3 tubes. It was found that the oscillating behavior differs depending on the inclination angle in the case of relatively small heat loads (less than 500W), in which the oscillation occurs intermittently. In the case of large heat loads (500W-1000W) the oscillation characteristics were almost independent of inclination angle, and the frequency increases with the heat load. Other detailed features of temperature fluctuations, such as auto-correlation functions and relationships between adjacent tubes, were examined.
