Abstract


Parallel simulations of air flow inside an aspiration chamber were performed with Fluent utilizing both Reynolds-averaged and large-eddy simulation approaches provided in this software. The finest mesh for the 3-D geometry considered in these studies contains slightly more than 2.6 million nodes, and computations were carried out with up to eight processors, the maximum number available under our Fluent license. The goals of the present study are: i) to assess accuracy of Fluent turbulence models in comparison with data from laboratory experiments involving aspirator flows, and ii) to determine effectiveness of parallelization of Fluent in the context of cluster machine architecture.
