โœฆ Synopsis

Time-dependent cross-flow was studied around cylinders with circular and noncircular cross-sections. The numerical approach for the analysis was a low-order panel method based on constant source and dipole values along each panel. The method was previously used successfully for several applications, such as calculation of the added mass and damping coefficients. In simulating the viscous time-dependent flow around the cylinder, the time-dependent wake feature of the code was used. For the circular and D-cylinders, the results agreed well with the experiments. Suggestions for improving the results for T-cylinders with angle of attack are included.

Unsteady flow around a circular cylinder at postcritical Reynolds numbers is simulated by the vortex method with a boundary-layer turbulence model. In the fractional step scheme, the vortex-in-cell method with a polar mesh is used for the convection of point vortices and random walks are superimpose
