TL;DR: In this article, the effect of subgrid scales on the resolved scales has been modeled by dynamic one equation subgrid-scale model and the simulated values of the mean axial, radial and tangential velocities along with the turbulent kinetic energy have been compared with the measured LDA data.

TL;DR: In this paper, simulations have been performed for three phase stirred dispersions using computational fluid dynamics model (CFD) and the effects of tank diameter, impeller diameter and impeller location on the impeller speed, particle size, solid loading and superficial gas velocity have been investigated over a wide range.

TL;DR: In this article, a review of the literature regarding CFD simulation of axial flow impellers is presented and the strengths and weaknesses of various turbulence models for axial-flow impellers are discussed.

TL;DR: Deshmukh et al. as mentioned in this paper performed experimental fluid dynamics as well as computational fluid dynamics (CFD) studies for hollow self-inducing agitator system and determined low pressure regions on the impeller blade by single phase CFD simulations.

TL;DR: In this article, the effect of different impeller designs (hollow self-inducing pitched blade down flow turbines of different blade angles (PBTD30, PBTD45, and self inducing modified double disc (MDD) impeller) and operating conditions such as solid loading (0-7 wt. %) and solid particle size (125-700 μm) on critical impeller speed for solid suspension (N CS), gas induction rate (Q G ) and overall gas hold-up ( ∈ G ).
