A discrete vortex method combined with the source distribution method was applied to the flow analysis around a rectangular cylinder accompanied by through-flow. The effects of kinematic viscosity ν on drag coefficient and Strouhal number were investigated. The value ν of 0.00001m2/s was the most appropriate one under our conditions. The ratio of vertical to horizontal length of a rectangular cylinder was changed as a calculational parameter. The drag coefficient CD was in agreement with the reported results. The calculations of the through-flow into the rectangular cylinder were carried out under the same conditions as those in the experiments in a two-dimensional water pool. The calculated and experimental values were satisfactorily in agreement. Consequently, it is shown that our numerical method is very useful in calculating the through-flow into the body.
