Numerical simulation of coupled heat transfer characteristics for flows at supercritical pressure [aircraft fuel flow]

This article describes a numerical model to simulate the flow and heat transfer at supercritical pressure of aircraft fuel fluid. A real-fluid model for thermophysical properties, such as density, enthalpy, specific heat, viscosity and thermal conductivity is implemented. The numerical validation of this proposed model, in conjunction with radiation and conjugate heat transfer models, is carried out for the coupled heat transfer against the experimental measurement of Jet-A and SF₆ at high pressures. The satisfactory comparison between prediction and measurement is obtained
