摘要：
A large-eddy simulation (LES) technique has been used for the calculation of an air flow past a heated square cylinder. The LES method is a conventional one with the Smagorinsky eddy-viscosity model, and the computational grid is small enough to be handled by workstations. The computed turbulent flow field quantities agree well with the experimental results reported by Lyn et al. (J Fluid Mech 304:285–319, 1995). Particular attention has been spent to the convective heat transfer and the prediction of the thermal fluctuations in case of a fluid with Pr = 0.71. The LES results agree well with the empirical correlations proposed by Hilpert and Sparrow et al. for the average Nusselt number.
