Numerical Research On The Hydrodynamic Characters Of A Circle Cylinder And Two Circle Cylinders In Tandem Arrangement In Uniform Cross Flow

The phenomenon of fixed cylinder and cylinders destroyed by vibration induced by vortex often happen in steady flow, so the research on the vibration by vortex is of important in the design of structures of ocean and offshore engineering. Many scholars have done much experimental research about this problem, but the results of experimental research was at low Reynolds numbers, at high Reynolds numbers there are a great deal of difficulties by experimental research.Whereas this problem, this paper calculates the hydrodynamic characters of a circle cylinder and tandem two cylinders in steady flow and moderate turbulence intensity at high Reynolds numbers (1.79E5
