A comprehensive study of secondary and tertiary vortex phenomena of flow past a circular cylinder: A Cartesian grid approach

Abstract: This study envisages undertaking a comprehensive simulation of the flow past an impulsively started circular cylinder with special emphasis on vortex dynamics in the secondary and tertiary level. A recently developed second order spatially and temporally accurate compact finite difference scheme on a nonuniform Cartesian grid has been used to discretize the transient Navier–Stokes equations governing the flow. The grid is generated in such a way that the cylinder boundary passes through the grid points, thus d… Show more

“…A quantitative comparison is also carried out in table 8. Computational results are compared with reference data [28,29,30,31,8,32,33,34,35,17,36,37,38]. Once again, the efficiency of the present scheme is evident from the proximity of our results with the well-established results available in the literature.…”

“…Finally, we carry out numerical simulation for the classical problem of heat transfer in the fluid flow over the stationary heated circular cylinder. The stationary heated circular cylinder is presumed to be of unit radius (R 0 = 1) and immersed in a fluid of infinite domain maintained at unit nondimensional temperature [28,29,30,31,8,32,33,34,35,17,36,37,38]. The cylinder is kept in a cross-flow having uniform velocity…”
