摘要：
Analysis of the aerodynamic drag of two blunt bodies located behind each other in a uniform flow is represented by one of the urgent problems of the aerodynamics of poorly streamlined bodies. Its practical value is to the necessity of predicting the aerodynamic characteristics of systems of poorly streamlined bodies, and to the tendency to organize the flow around bodies of revolution by using the premeditated formation of developed circulation zones near their surface in order to improve their characteristics. The effect of reducing the drag of two disks is investigated by using difference modeling of their flow by using the two-parameter k- epsilon turbulence model.
