High order accurate methods in numerical simulation of hypersonic heat transfer

Influencing factors of hypersonic heat transfer simulation were studied with the blunt cone model. The connection between heat transfer computation and wall-normal grid Renolds number was established. Stable and accurate heat transfer result was acquired with high-order interpolation methods. A variety of schemes and limiters were evaluated to research the influence of numerical diffusion on heat transfer calculation. Five-order weighted essentially non-oscillatory (WENO) scheme was employed in heat transfer computation and high-order accurate methods for hypersonic heat transfer prediction were established. It shows that high-order scheme can not only broaden the grid Reynolds number range but also reduce the dependence on space discretization methods in heat transfer computation.
