Abstract

In this work the large-eddy simulation (LES) is used to investigate incompressible flow around a sphere with trip wire. The sphere is located in a channel with square cross-section, and the bulk Reynolds number is Re = 50 000. The computational effort implied by demands for sufficient spatial and temporal resolution of the flow structures requires parallel runs on a high-performance computer. The numerical results are compared to the experimental ones in order to provide reliable data for testing, calibrating and improvement of statistical turbulence models. The time-averaged LES-results and the measured data obtained by the laser-Doppler-anemometry (LDA) for the velocity and the Reynolds-stress components are in reasonable agreement. Accuracy of the predicted mean-flow velocity component is particularly good. Comparison of the Reynolds stresses shows certain deviations in the far wake, agreement is however acceptable from the qualitative point of view.
