Abstract:
The endothermic hydrocarbon fuel as the coolant in the airbreathing hypersonic vehicles, its working temperature could be up to 750 ℃.The effective cooling capacity and coking characteristics of hydrocarbon fuel at high temperature conditions are crucial for the regenerative cooling technology.An experimental evaluation system for the regenerative cooling performance of endothermic hydrocarbon fuel was constructed to realize the measurement and evaluation of heat sink, coking characteristics and heat transfer characteristics.The heat sink was measured by the thermal balance method.Basically, the heat sink could be 2.0 MJ/kg for fuel at temperature of 600 ℃ and 3.5 MJ/kg at 750 ℃.Coking propensity was measured by hydraulic resistance method at laminar conditions.The equivalent inner diameter of the test tube before and after coking test could be obtained by the poiseulle’s law.Then the average coking thickness could be obtained from the inner diameter before and after coking test.Heat transfer characteristics were evaluated by comparing the wall temperature behavior at the same outlet fluid temperature for different fuels.The above experimental evaluation methods provide an effective evaluation mean for the selection and development of endothermic hydrocarbon fuel.
