Experimental and computational analysis of a cyclone separator with a novel vortex finder
TL;DR: In this paper, the performance of notched vortex finders in a cyclone separator with a tangential inlet was evaluated, and the results showed that the results of the notched finders greatly improved over the separation performance of the original separator.

Computational and Experimental Analysis of Axial Flow Cyclone Used for Intake Air Filtration in Internal Combustion Engines
Tadeusz Dziubak,Leszek Bąkała +1 more
TL;DR: In this article, the authors used the commercial software Ansys Fluent to evaluate axial flow cyclones at a constant inlet velocity of 10 m/s and found that the separation efficiency was increased with an increase in the separation length and a decrease in the diameter of the cyclone inlet tube.

A dynamic subgrid‐scale eddy viscosity model
TL;DR: In this article, a new eddy viscosity model is presented which alleviates many of the drawbacks of the existing subgrid-scale stress models, such as the inability to represent correctly with a single universal constant different turbulent fields in rotating or sheared flows, near solid walls, or in transitional regimes.
