Abstract
The heat transfer of the kerosene under supercritical pressure was investigated through experiment.According to the experimental results,the heat transfer curve of the kerosene under supercritical pressure was plotted.The results show that kerosene heat transfer under supercritical pressure from low to high temperature goes through the following four periods:(1) the normal heat transfer: in this region,the tube wall temperature and the kerosene temperature are lower than the critical temperature;(2) heat transfer enhancement period: in this region,the tube wall temperature arrives at the critical temperature,similar boiling heat transfer happened;(3) heat transfer deterioration: in this region,the temperature is higher than the temperature that the specific heat reaches the maximum value and decreases slowly after the maximum;(4) the second heat transfer enhancement: after the heat transfer deterioration period,when the temperature is even higher,both the specific heat and the conduction coefficient rises slowly,and the second heat transfer enhancement come.
