“…Additionally, when the fuel near the wall was heated to above 600 K, the fuel became supercritical and heat convection was significantly enhanced. Enhancement in the convective heat transfer of kerosene flow when approaching its critical temperature has been observed in many of other studies [9,15,25] under much larger wall heat fluxes (500-1000 W=cm 2 ). However, it has to be pointed out that, for the current study with lower heat fluxes, neither a sudden change in heat convection, nor pressure oscillation and the associated flow instability, were observed, as found in the literature [9,15,25].…”

“…It is known [6,7] that supercritical fuel exhibits a liquidlike density and a gaslike diffusivity. In addition, the variations of many of the fuel thermodynamic and transport properties, such as density, specific heats, viscosity, and thermal conductivity, with temperature are complex, depending on the thermophysical conditions [8,9]. Taking China no.…”

The heat transfer characteristics of China no. 3 kerosene were investigated experimentally and analytically under conditions relevant to a regenerative cooling system for scramjet applications. A test facility developed for the present study can handle kerosene in a temperature range of 300-1000 K, a pressure range of 2.6-5 MPa, and a mass flow rate range of 10-100 g=s. In addition, the test section was uniquely designed such that both the wall temperature and the bulk fuel temperature were measured at the same location along the flowpath. The measured temperature distributions were then used to analytically deduce the local heat transfer characteristics. A 10-component kerosene surrogate was proposed and employed to calculate the fuel thermodynamic and transport properties that were required in the heat transfer analysis. Results revealed drastic changes in the fuel flow properties and heat transfer characteristics when kerosene approached its critical state. Convective heat transfer enhancement was also found as kerosene became supercritical. The heat transfer correlation in the relatively low-fuel-temperature region yielded a similar result to other commonly used jet fuels, such as JP-7 and JP-8, at compressed liquid states. In the high-fuel-temperature region, near and beyond the critical temperature, heat transfer enhancement was observed; hence, the associated correlation showed a more significant Reynolds number dependency.

“…In normal conditions, it is possible that the cooled media of the fuel is beyond the critical region [2][3]. Under supercritical and pseudo-critical region, the dramatic variation of thermophysical properties of the fuel would make the heat transfer characteristics distinguished from the subcritical conditions significantly [4][5][6][7]. Therefore, it is important to investigate the characteristics of heat transfer and frictional resistance kerosene RP-3 under supercritical condition both experimentally and numerically.…”
