Abstract
In the engineering practice we can find many examples of the combination of bluff bodies, such as the building group, tracter-trailer as well as bridge deck and pier, etc. The model which is investigated in this paper consists of a circular cylinder and a disk placed coaxially upstream of the cylinder with the flat face The geometry of the model is simply axisymmetric with sharp edge, which fixes the separation point of the flow. The vortex shielding effect of the disk can reduce the drag of a disk-cylinder combination considerably and its possible practical application make us pay more attention to the study the flow pattern and the drag of such a configuration. Some encouraging results were obtained by Koenig and Roshko [1].
