本文用涡量-矢势方程研究了三维不可压缩层流绕立方体的流动。数值解的涡量输运方程耦合到离散泊松方程的标量和矢量势的半隐式有限差分近似得到使用八色SOR算法。计算是在雷诺数从10到100的范围内进行的。预测的阻力和其他流动特性与实验结果一致，包括从立方体下降实验进行本研究。
Three-dimensional incompressible laminar flow around a cube is investigated using the vorticity–vector potential formulation of the equations of motion. Numerical solutions to a semi-implicit finite difference approximation to the vorticity transport equation coupled to discrete Poisson equations for the scalar and vector potentials are obtained using an eight-colour SOR algorithm. Calculations are done at a range of Reynolds numbers from 10 to 100. The predicted drag and other flow characteristics are found to agree well with experimental results, including those from a cube drop experiment performed for the present study.
