| Abstract | A two-dimensional finite volume method with unstructured mesh is used to simulate the flow around four square cylinders in a square configuration at low Reynolds numbers.The vorticity field, drag and lift coefficients, and Strouhal number are resolved at different spacing ratios. The vortex-shedding process and fluid-structure interactions of four square cylinders are analyzed at Reynold number of 100. The results show that the spacing ratio has important effect on the drag and lift coefficients. The accuracy of the numerical scheme are validated against other numerical and experimental data. |
