242 Grid dependence of frequency of Karman vortex sheets
Details
Karman vortex sheets from a two dimensional circular cylinder at low Reynolds number are calculated using node-centered Finite Volume Method and unstructured mesh. In order to prepare for a coupling analysis between flow and structure oscillation, dependence of mesh density for frequency of vortex shedding are investigated in this paper. The results show that it is possible to capture a periodic vortex shedding using a sufficient quantity of unstructured hybrid mesh (mixture of prism and hexagon mesh).
