| 中文摘要 | Through numerical simulations, effects of a higher Reynolds number (105) and the introduction of perforation at a lower Reynolds number (102) on flows past a circular cylinder with the conic disturbance are investigated. Particularly, circular holes are located on and uniformly distributed around the peak of the conic shroud. Results have been shown that the higher Reynolds number of 105has little effect on qualitative variations of the drag and lift coefficients and the frequency of vortex shedding in most cases, which are almost similar to those at lower Reynolds numbers, as well as the introduced perforation. Nevertheless, there are still several exceptional cases with different hydrodynamic parameters resulted from the introduction of perforation. And different disturbance regimes and vortex patterns in the near wake for these cases are identified and presented in detail.
