Abstract

Three-dimensional fluid flow around two circular cylinders in tandem arrangement is computed by finite difference method without any turbulence model. The overlapped grid technique is employed in order to catch the flow interference between two tandem cylinders. As the result, the numerical abrupt change of drag coefficients is good agreement with the previous experimental ones.
