我们提出了一种能够处理多个共旋转参考系中的流动的时空有限元方法。由于对所有自由度使用等阶插值,因此应用了伽辽金/最小二乘稳定化。我们给出了所涉及的方程的详细推导,介绍了变分形式,给出了稳定参数,并讨论了实现问题。二维和三维的数值算例显示了该方法的通用性和有效性,如果旋转部件的稳态行为足以进行CFD分析。版权所有©2015 John Wiley & Sons, Ltd
We present a space‐time finite element method capable of dealing with flows in multiple co‐rotating reference frames. Since equal order interpolation is used for all degrees of freedom, Galerkin/least‐squares stabilization is applied. We give a detailed derivation of the equations involved, introduce the variational form, present the stabilization parameters, and also discuss implementation issues. Numerical examples in 2D and 3D show generality and efficiency of the method, if steady‐state behavior of rotating components is sufficient for the CFD analysis.
