Flow distribution inside an electrostatic precipitator : effects of uniform and variable porosity of perforated plate by Shah Haque( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

This paper presents a numerical flow model applied to a 3D geometry of an electrostatic precipitator (ESP). The flow simulation is performed by using the computational fluid dynamics (CFD) code FLUENT. Realizable k-Sf model for turbulence condition inside the ESP is applied. In the simulation, the perforated plates are modeled as thin porous media of finite thickness with directional permeability. Perforated plates with both uniform porosity and variable porosity are considered for simulation. The results of the simulation are discussed and compared with on-site measured data supplied by the local power plant. The simulated results show reasonable agreement with the measured data
Electrochemical characterisation of the parallel disk device by Ian R McNeilly( )

1 edition published in 2006 in English and held by 1 WorldCat member library worldwide

A novel Parallel Disc Device (PDD) has been designed and built at the Process Engineering and Light Metals (PELM) Centre of Central Queensland University. The device, built primarily to study aspects of flow accelerated corrosion, consists of two discs separated by a precision controlled gap. The bottom disc (which accommodates the working electrode) is immobile while the top disc rotates. The PDD is capable of generating very high wall shear rates and the shear of liquid at the working electrode is purely tangential as long as flow between the discs remains laminar
A numerical approach to improve the flow model of an electrostatic precipitator by Shah Haque( )

1 edition published in 2008 in Undetermined and held by 1 WorldCat member library worldwide

This paper presents a numerical approach to develop an accurate Computational Fluid Dynamics (CFD) model for an electrostatic precipitator (ESP). The flow simulation was performed by using the CFD code FLUENT. Numerical calculations for the air flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modelled using the realizable k-e turbulence model. Simulation with uniform (ideal) velocity profile is compared with that with measured (real) velocity profile at the inlet boundary. The model developed by using the measured velocity profile at its inlet boundary showed more reliable simulation results
A numerical model of an electrostatic precipitator by Shah Haque( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

This paper presents a Computational Fluid Dynamics (CFD) model for a wire-plate electrostatic precipitator (ESP). The turbulent gas flow and the particle motion under electrostatic forces are modelled using the CFD code FLUENT. Numerical calculations for the gas flow are carried out by solving the Reynolds-averaged Navier-Stokes equations and turbulence is modelled using the k-Sf turbulence model. An additional source term is added to the gas flow equation to capture the effect of electric field. This additional source term is obtained by solving a coupled system of the electric field and charge transport equations. The particle phase is simulated by using Discrete Phase Model (DPM). The results of the simulation are presented showing the particle trajectory inside the ESP under the influence of both aerodynamic and electrostatic forces. The simulated results have been validated by the established data. The model developed is useful to gain insight into the particle collection phenomena that takes place inside an industrial ESP
Analysis of flow patterns inside the stirred tank used in alumina refinery by Clemont W Hooley( )

1 edition published in 2008 in English and held by 1 WorldCat member library worldwide

In this study, the turbulent flow patterns inside two model tanks were analysed using video camera in order to determine possible causes of undesirable formations of gibbsite sediments that are occurring at the bottom of precipitation tanks in the alumina refinery. The two tanks were geometrically similar and were of 1500L and 200L respectively each with a height equal to 1.2D and agitated with three pitched blade impellers of diameter 0.5D. The flow patterns were highlighted by the addition of polystyrene particles and were analysed through video camera recordings. The tanks revealed complex flow patterns that were not able to be fully analysed through the use video cameras. However, flow patterns were observed and analysed on a visual basis. Of notice was a complex region of flow that contained erratic fluctuations between radial and axial flow patterns. The erratic behaviour of this complex region of flow frequently amplified out to the tank walls and bottom causing brief stagnation periods and periods of uncharacteristic flow patterns. These results were verified with both tank sizes
A parallel disc device for studying corrosion under intense flow conditions by Subaschandar Rao( )

1 edition published in 2007 in English and held by 1 WorldCat member library worldwide

A novel electrochemical Parallel Disc Device (PDD) has been designed and built at the Process Engineering and Light Metals (PELM) Centre of Central Queensland University. This device, built primarily to study aspects of flow accelerated corrosion, consists of two discs separated by a precision controlled gap. The bottom disc (which accommodates the working electrode) is immobile while the top disc rotates and enables a flow of liquid between the discs. The gap between the discs can be set within the range 0.050 to 5.000 mm with a precision of 0.005 mm. The PDD is capable of generating very high wall shear rates and the shear of liquid at the working electrode is purely tangential as long as flow between the discs remains laminar. This paper presents results of preliminary Computational Fluid Dynamics (CFD) characterisations of the fluid flow in the gap between the parallel discs. In addition we present some results for the electrochemical reduction of dissolved oxygen at a copper PDD electrode
