Reproducibility of flow past two-dimensional rectangular cylinders in a homogeneous turbulent flow by LES
AbstractA large-eddy simulation technique has been applied for prediction of flow past rectangular cylinders influenced by free-stream turbulence. A stochastic method was used to generate homogeneous turbulence with specified power and cross spectra in the oncoming flow. It has been found that the buffeting effects due to the inflow turbulence on front surface of cylinders are predicted well. In case of a cylinder of small length-to-height ratio (B/D=1.0), just Strouhal number increases slightly and for large (B/D=2.5), enhanced turbulent mixing causes reattachment of separated shear flow on the cylinder side. These are in good agreement with the results of previous experimental studies, and the present method appears to be sufficient for practical applications.
