Abstract

The planar oscillatory flow past a smooth circular cylinder at low Keulegan-Carpenter numbers (K ≤ 4) is modelled using a modified version of the Reynolds-averaged Navier-Stokes (RANS) finite-volume solver developed by Leschziner, Lien and co-workers at UMIST. This is an implicit scheme which has been modified to achieve second-order accurate time-stepping through the use of Gear's second-order method. The low-Reynolds-number k-ε model of Launder and Sharma is used to model turbulence. The results obtained using this method are compared with previous experimental measurements and numerical results. In particular the results are in encouraging correspondence with the experimental data of Bearman et al. and Sarpkaya.
