An experimental study and a numerical simulation are presented concerning the three dimensional turbulent flow of air in a cyclone separator in the region underneath the vortex finder. The computations are carried out using the Fluent CFD code. The turbulence effects on the mean flow are taken into account using the standard k- model and the standard Reynolds stress Model (RSM). https://cosmeticssquadets.shop/product-category/blood-glucose-monitoring/
