SIMULATION OF FLOW PAST TWO TANDEM CYLINDERS USING DETERMINISTIC VORTEX METHOD
Abstract
The vortex method is a direct numerical simulation method for solving the Navier-
tokes equations. In order to reveal the influence of Reynolds number and distances
etween the cylinders, the incompressible flow past a pair of tandem cylinders
s solved on the base of the vortex method. The results show that for the
low past two tandem cylinders, there is a critical distance of the tandem cylinders.
ver the critical distance, the flow field will have a sudden change, and the
rag coefficient, lift coefficient and Strouhal number will also change dramatically.
he critical distance will diminish as the Reynolds number rises.
