Computational Analysis of Swirling Pipe Flow

Popis výsledku v původním jazyce

Swirling pipe flow was investigated using advanced scale-k-w SST SAS). The analysis of turbulent swirling fluid motion in pipe focuses mainly on the model prediction capabilities. For validation purposes were used experimental data from (Pashtrapanska et al., 2006). Global instability was produces by a contraction ring placed downstream of swirl generator. Predicted data were sampled at several distances from the swirl generator to compare them with experiment. Repeated simulations were performed on several computational grids involving unstructured and structured meshes. Grid tests revealed strong influence of computational grid on fluid flow behaviour predicted by the model. Most distinguishing feature of the predictions is asymmetry of mean velocity profiles, which is contrary to results obtained from experiment.
