Numerical simulation of three-dimensional unsteady viscous flow past finite cylinders in an unbounded fluid at low intermediate reynolds numbers

Abstract

The flow past finite circular cylinders for Reynolds numbers 40 and 70 were simulated by numerical solutions of the incompressible Navier-Stokes equations. A nonuniform cartesian grid was used for the computation. The numerical scheme used was the QUICK scheme. Comparisons with experimental measurements of Jayaweera and Mason show that the results of the simulation are satisfactory. Features of three-dimensional unsteady viscous flow past finite cylinders, such as the pyramidal wake and the three-dimensional von Karmen vortex street, are successfully simulated.
