“…Compared to cryogenic hydrogen, heavy hydrocarbon fuel is safer and much simpler to use; moreover, it could conduct to smaller vehicles because its density is higher than that of cryogenic fuel [4]. Hence, engines using hydrocarbon as fuel have a promising application prospect, as can be seen from the fast development of hydrocarbon-fuelled scramjet in the recent years [5,6]. For a supersonic regime, especially a hypersonic regime, the operating process in the engines with hydrocarbon fuel used as coolant is much complex, and the accurate evaluations of engine performance in both the design process and the analysis studies are vital if conceptual engines are to be successfully developed into complete ones in good time [7].…”

A one-dimensional cooling channel model is proposed using unsteady partial differential equations (PDEs) and taking into account the strong dependencies of hydrocarbon fuel properties on temperature and pressure. The model can be used to evaluate the performance of channel cooling using hydrocarbon fuel as coolant under supercritical pressures, and to guide the design of a thermal protection system for aerospace application. Meanwhile, a graphical simulation method is developed to directly solve the proposed model using Simulink by converting the PDE to a set of ordinary differential equations without any need to write program codes. The graphical method can reduce the substantive work resulting from program codes writing and debugging and bring about interactions with users through its graphical user interface. In order to show the usability of the proposed model and the developed graphical method, n-pentane, a typical hydrocarbon fuel, is taken as an example to run two simulations for steady and transient calculations. The developed graphical simulator for channel cooling is verified by comparing the calculation results with the experimental data of an electrical heating tube. It is believed that this investigation will pave the way for implementation of the graphical simulation of the whole cooled propulsion system used for supersonic or hypersonic flights.

In order to study the regenerative cooling mechanism, a three-dimensional numerical method for supercritical heat transfer of hydrocarbon fuels was established based on the Navier-Stokes equations and a thermophysical properties evaluation code. The supercritical heat transfer behavior of n-decane inside an electrically heated tube and n-dodecane inside a fuel-cooled panel has been computed. Detailed distributions of outer wall temperature and fuel temperature were obtained. The corresponding measurements are adopted to validate the numerical method. The relative deviations of the computational outer wall temperature from the test results are within 6.8%, and those of the fuel temperature are within 1%. Those indicate that the numerical method is reliable, and can be used as an effective tool to investigate the supercritical heat transfer of hydrocarbon fuels.
