Cd vs re for a cylinder
WebNov 20, 2015 · I am testing transient flow around a circular cylinder for Reynolds number of 8.000. In literature it is found that the experimental values of Cd is +-1.2, for this Reynolds number. I am obtaining Cd of about 1.6 - 1.8. I have made all my mesh in ICEM CFD and tested several in order obtain a result independent of the mesh. WebCoefficient of Drag given Reynolds Number formula is defined as constant which depends on reynolds number for calculating drag force is calculated using Coefficient of drag = 24/ Reynolds Number.To calculate Coefficient of Drag given Reynolds Number, you need Reynolds Number (Re).With our tool, you need to enter the respective value for …
