摘要
本文建立了高超声速飞行器前体的三级折转结构外形。针对球锥体模型,通过对模型进行有限元离散,并采用pointwise方法划分了网格;基于CFD/CTD耦合方法,计算了在不同攻角下球锥体的表面温度以及锥体母线上的最大温度和最小温度,显著提高了计算效率。
A kind of three-stage turnover configuration is built for a hypersonic vehicle forebody.Finite volume method(FVM)is used to discretize the sphere-cone model,and pointwise method is used to divide the grids.Based on CFD/CTD coupling method,the surface temperature of the sphere-cone and the maximum and minimum tempretures of the generating line on the sphere-cone model at different attack angles are computed,and the computation efficiency is improved significantly.
