| 摘 要： | 利用spalan-Allmaras湍流模型对三角翼一身组合体绕流流场进行数值模拟，并与国外风洞试验数据进行比较，验证了此湍流模型在超音速复杂流动计算中的有效性．同时采用基于密度的隐式求解器，数值离散格式采用二阶迎风格式，对十字形布置的4片弧形尾翼弹超音速流场进行了数值模拟．数值模拟结果给出了弧形翼附近的流场结构，并对弧形翼凹凸表面的压力分布做了详细分析，得出了弧形翼在零攻角下产生升力的机理．

| Abstract: | Spalart-Allmaras turbulent model is used for the numerical simulation of projectile configuration with four wrap-around fins in supersonic speed.The simulation results are compared with the experiment data obtained from the wind tunnel abroad,and the validity of Spalart-Allmaras turbulent model in supersonic complicated flow is verified with DERA body-wing configuration.The implicit solver based on density is used with 2nd upwind numeric discrete scheme for the numerical simulation of supersonic flowfield o... |
