ABSTRAKT

This paper presents an experimental study of the correlation between liquid motion and temperature change in an oscillating heat pipe (OHP). The images of the liquid motion were made using the neutron imaging technique. An algorithm to calculate the vapor and liquid fractions at each position of the OHP from the images has been developed. By comparing the average liquid fractions and the temperature data in the evaporator, it is shown that a quick liquid motion is synchronized with a quick temperature change. By comparing the distance from the two-phase interface to the edge of the evaporator with the vapor portion length and temperature, this study concludes that the vapor volume changes are directly related to those of temperature. A decrease in the temperature was observed before it increased due to the liquid motion. This temperature drop could also be due to thin film evaporation.
