Thermal interaction between an impinging hot jet and a conducting solid surface
Abstract
Poweredlift aircraft may produce severe hightemperature environments which are potentially damaging to a landing surface or the aircraft. The interaction betweean the high temperature flow field and a nonadiabatic landing surface is analyzed with a coupled computational fluid dynamics/solid thermal conduction computer code, HOTJET. The HOTJET code couples timeaccurate, implicit, factored solution schemes for the governing fluid dynamics equations (Reynoldsaveraged NavierStokes equations) to the unsteady thermal conduction equation, which governs heat flux within a solid. HOTJET is validated against exact solutions to the thermal conduction and NavierStokes equations. Firstofakind results are included which show the impact of surface material properties on the fluid physics and the coupled fluid/material thermal fields.
