Computational Fluid Dynamic Study of the Flow Downstream of the Swirl Generator Using Large Eddy Simulation

Original language description

Computational study of swirl generator apparatus is carried out commercial software Ansys Fluent v.14. employing Large Eddy Simulation (LES) model for turbulence modelling. Computational domain of swirl generator includes approximately 13 million of cells, consists of straight inlet pipe, swirl generator, conical diffuser with extended outlet and corresponds with real part of test rig situated in laboratory of V. Kaplan Dept. of Fluid Engineering, Faculty of Mechanical Engineering, Brno University of Technology. Swirl generator (see fig. 1) is device with ten shaped blades fixed around inner spike and situated in front of connected straight conical diffuser so that generates swirling flow similar to one occurring in draft tube (outlet diffuser) of Francis turbine operated at partial load (flow rate lower than optimal). This flow configuration is related to formation of so called vortex rope. Vortex rope is spiral-shaped, sometimes cavitating structure (water evaporated due to low pressure) w
