Journal ArticleDOI
Numerical prediction of flow fields in baffled stirred vessels: A comparison of alternative modelling approaches
TL;DR: In this article, numerical simulations of the flow field in baffled mixing tanks, based on three alternative methods, are presented and discussed, where the impeller is not explicitly simulated, and its effects are modelled by imposing suitable, empirically derived, boundary conditions to the external flow.
Journal ArticleDOI
Particle drag coefficients in turbulent fluids
TL;DR: In this paper, a new experimental technique for measuring average particle drag coefficients in turbulent media is presented based on a direct measurement, by means of a suitable residence time technique, of the settling velocity exhibited by a cloud of particles.
Journal ArticleDOI
Large-eddy simulation of turbulent flow in an unbaffled stirred tank driven by a Rushton turbine
TL;DR: In this paper, the turbulent flow field generated in an unbaffled stirred tank by a Rushton turbine was computed by large-eddy simulation (LES) and the Smagorinsky model was used to model the unresolved sub-grid scales.
Journal ArticleDOI
Turbulent flow in closed and free-surface unbaffled tanks stirred by radial impellers
TL;DR: In this paper, the three-dimensional turbulent flow field in unbaffled tanks stirred by radial impellers was numerically simulated by a finite-volume method on body-fitted, co-located grids.
Journal ArticleDOI
Bench-Scale Investigation of Inclined Dense Jets
TL;DR: In this paper, experimental data on the geometry of dense inclined jets issuing in a lab-scale glass rectangular tank are presented, where the surrounding fluid was always tap water at room temperature while the dense jets were water solutions of NaCl.
