Three-Dimensional Numerical Study of Supercritical Heat Transfer of Cryogenic Methane in an Engine Cooling Channel

摘要：

A three-dimensional numerical study of the turbulent convective heat transfer of the cryogenic methane flowing inside a square engine cooling channel under supercritical pressures has been systematically conducted. Numerical results indicate that increasing the fluid pressure would result in enhanced heat transfer of the cryogenic methane under supercritical pressures; At the pseudo-critical temperature under a corresponding supercritical pressure, drastic property variations could cause heat transfer deterioration and sharp wall temperature increase at a high wall heat flux of 7 MW/m2; A modified Jackson and Hall heat transfer equation, which can be used for supercritical heat transfer calculations of the cryogenic methane, has been successfully established in this paper.
