摘要：
In order to understand the aviation kerosene's deposition characteristics under high temperature conditions, the RP-3 aviation kerosene's deposition boundary temperature and characteristics under static state, the influences of different fuel inlet conditions and wall temperatures were studied by test. The results indicated that the deposition boundary temperature under static state was between 437-450K, and the deposition rate decreased with the increase of test time. Increasing the flow velocity, and decreasing the fuel inlet temperature and the wall temperature can effectively reduce the deposition amount, and decreasing the fuel inlet temperature had the most effective impact. From the perspective of time scale, deposition accumulated slowly in the early stage, but increased significantly when a certain deposition amount had been formed. Taking the 400K fuel inlet temperature, 800K wall temperature and 0.5m/s flow velocity test as example, the deposition amount of 8h and 12h test was about 1.5 times and 7 times that of the 4h test, respectively. © 2020, Editorial Department of Journal of Aerospace Power.
