Abstract: In this study, the turbulent characteristics about the three dimensional circular cylinder of limited height 45000 by the Detached Eddy Simulation (DES). Numerical analysis of the proposed model is to be compared with the theoretical analysis. The results are showed the DES Model better for the LES for the calculation of the flow past. The investigation of the complicated flow structure is analyzed and studied in this study. The DES Model is very efficient for the analysis of the flow characteristics and also, the complexity of the flow model is reduced by the proposed DES Model.
