提出了一种求解非定常不可压流动的分步有限元格式。由于计算过程中没有引入高阶项，因此该方法适用于非线性多维问题。对二维圆柱绕流的非定常流动进行了分析，预测了不同雷诺数下圆柱绕流的流型。预测的旋涡脱落的Strouhal数与以前的结果吻合得很好。
A fractional step finite element scheme is proposed for unsteady incompressible flows. Since no higher order terms are introduced in the presented computation, this method is suitable for nonlinear multi dimensional problems. The unsteady flow around a two dimensional circular cylinder was analyzed to predict the flow patterns for different Reynolds numbers. The predicted Strouhal number for vortex shedding is in good agreement with previous result.
