    Numerical Simulation of Compressible Flows in Irregular Geometries

    • 摘要: 将不可压缩流动的SIMPLE算法推广到可压缩流动的计算中。将二维直角坐标系和轴对称坐标系下的可压缩流动的控制方程用统一的方程式表达,在贴体网格中利用有限体积法进行离散,编制了通用的求解程序。对带有凸包的通道可压缩流动和轴对称坐标系下的马赫反射问题进行了数值模拟,得到的结果与相关文献中的结果吻合,表明了所提算法的正确有效性。

       

      Abstract: The SIMPLE algorithm for incompressible flows is extended to calculate compressible flows. The governing equations of compressible flows in both Cartesian and axisymmetric coordinates are arranged into an unified form. The governing equation in curvilinear coordinates is discretized using a finite volume method and is solved using a pressure correction procedure. The compressible flows in a channel with an arc bump and the flows in a nozzle with shock wave reflections are calculated, and are validated by bench mark numerical solutions.
