Computational fluid dynamics simulation of the flow patterns and performance of conventional and dual-cone gas-particle cyclones
One of the main concerns of researchers is the separation of suspended particles in a fluid. Accordingly, the current study numerically investigated the effects of a conical section on the flow pattern of a Stairmand cyclone by simulating single-cone and dual-cone cyclones. A turbulence model was used to analyze incompressible gas-particle flow in the cyclone models, and the Eulerian–Lagrangian...
متن کاملCFD Study and Energy Optimization of Industrial Double-Cyclone in HDPE Drying Process
In this paper, a double-cyclone is used as a gas-solid separator in the fluid bed-drying process to prepare dry HDPE powder from a wet feed of 56000 kg/hr. The quality of dry HDPE depends mainly on particles behavior and flow pattern in the dryer which affect the double-cyclones as an effective equipment in this process. Controlling of the inlet carrier gas causes excellent flow pattern, desire...

With the increase of computer power and advancement of modeling software, the study of turbulent gas-particle flow problems using computational fluid dynamics (CFD) techniques is gradually becoming attractive in the engineering field. Two basic CFD approaches are used to simulate the gas-particle flow, i.e. the Eulerian-Lagrangian model and the EulerianEulerian model. The aim of this thesis is ...
متن کاملApplication of CFX to Implantable Rotary Blood PumpsSuspended by Magnetic Bearings
The University of Virginia has been utilizing CFX series software to design and analyze implantable rotary blood pumps for several years. Besides the basic computational fluid dynamics (CFD) calculations and simulations of fluid field for blood pumps, several advanced CFD models were used which were relevant to the analysis of blood pumps or magnetic bearings. A Lagrangian Particle Tracking stu...
متن کاملMultiphase flow and tromp curve simulation of dense medium cyclones using Computational Fluid Dynamics
Dense Medium Cyclone is a high capacity device that is widely used in coal preparation. It is simple in design but the swirling turbulent flow, the presence of medium and coal with different density and size fraction and the presence of the air-core make the flow pattern in DMCs complex. In this article the flow pattern simulation of DMC is performed with computational fluid dynamics and Fluent...
