Abstract
A LES Large Eddy Simulation is performed to study the flow past two side-by-side circular cylinders at a Reynolds number of 5800, based on the free-stream velocity and the cylinders diameter. The centre-to-centre transverse pitch ratio T/D is varied from 1.5 to 3. Both cylinders are slightly heated and the small amount of heat can be treated as a passive scalar. The numerical simulations are in good agreement with experimental observations.
