Abstract

Direct Numerical Simulations (DNS) of flow over and heat transfer to the stagnation region of a circular cylinder have been performed at a Reynolds number of Re D =140 000 - based on the far field velocity and the diameter of the cylinder D -. To avoid the formation of a vortex street, behind the cylinder a splitter plate was introduced. The computations were carried out on the NEC SX-8 using up to 192 processors and 746.5 million grid points. Two simulations were performed: A two-dimensional, fully laminar simulation to obtain a base-line solution and a fully three-dimensional simulation to address the influence of oncoming free-stream fluctuations on the heat transfer from the stagnation region of the heated cylinder. The incoming free-stream turbulence stems from a separate simulation of isotropic turbulence in a box. Compared to the fully laminar simulation, the addition of free-stream fluctuations at the inflow plane was found to lead to an increase in heat transfer in the stagnation region of the cylinder by 66%.
