| 摘 要： | 为研究弹性体在稠密大气中的分离问题,基于非结构网格,采用运动网格与局部网格重构相结合的方法求解大位移相对运动的流场,并耦合6自由度刚体运动方程得到整流罩的运动.非定常流动方程使用格心有限体积法进行空间离散,并运用LU-SGS进行求解.应用标准算例验证该方法的准确性,并用于某整流罩飞行轨迹的计算.结果表明结构变形可能会使...

| Abstract: | To study elastomer separation in dense atmosphere,based on unstructured mesh,the method combining moving mesh with local re-meshing is used to solve the flow field of relative movement with large displacements,and the fairing movement is calculated by coupling rigid body motion equations with six degree of freedom.The unsteady flow equations are discretized in space by cell-center finite volume method and solved by LU-SGS.A standard numerical example is employed to validate the accuracy of the method.Then a... |
