Abstract:Experimental studies on the thermophysical property parameters in the temperature range of -10℃~40℃ were carried out for hydrocarbon fuels widely used in aircraft engines. Taking aviation kerosene provided by a testing center as the test sample, its density, viscosity, compression coefficient and expansion coefficient at different temperatures were tested. The results show that the viscosity and compression coefficient of aviation kerosene are positively correlated with temperature, while the density is negatively correlated with temperature, and the expansion coefficient of aviation kerosene shows complex fluctuations with increasing temperature. In this basis, the mathematical prediction models of density, viscosity, compression coefficient and expansion coefficient with temperature were proposed by combining the measurement results of each parameter at standard temperature.
