Description
Summary:The possibility of decoupled analysis of flow-field and heat transfer for a solid structure was investigated using numerical simulation of conjugate problem on hypersonic flow and heat transfer for a blunted cone made of heat-conducting material. The considered cones had semi vertex angle ϕ≈7 ° and two radii of blunting: r1иr2=23r1. This form is typical for noses of modern hypersonic aircraft. The ANSYS FLUENT software package was used to simulate a laminar flow with developed physicochemical models of nonequilibrium air (a five-component gas mixture was considered: O2; N2; O; N; NO) and S2S built-in model of radiative heat transfer. The accuracy of the decoupled analysis was evaluated as a result of comparison with the solution of the conjugate problem on flow-field and internal heat transfer.
