Laser flow visualization and velocity fields by particle image velocimetry in an electrostatic precipitator model
Although improving electrostatic precipitator (ESP) collection of fine particles (micron and submicron sizes) remains of interest, it is not yet clear whether the turbulent flow patterns caused by the presence of electric field and charge in ESPs advance or deteriorate fine particle precipitation process. In this paper, results of the laser flow visualization and Particle Image Velocimetry (PIV...
متن کاملParticle dispersion in synthetic turbulent flows
We study particle dispersion advected by a synthetic turbulent flow from a Lagrangian perspective and focus on the two-particle and cluster dispersion by the flow. It has been recently reported that Richardson's law for the two-particle dispersion can stem from different dispersion mechanisms, and can be dominated by either diffusive or ballistic events. The nature of the Richardson dispersion ...
متن کاملComparison of Turbulent Particle Dispersion Models in Turbulent Shear Flows
This work compares the performance of two Lagrangian turbulent particle dispersion models: the standard model (e.g., that presented in Sommerfeld et al. (1993)), in which the fluctuating fluid velocity experienced by the particle is composed of two components, one correlated with the previous time step and a second one randomly sampled from a Wiener process, and the model proposed by Minier and...
متن کاملSome Aspects of Turbulent Relative Particle Dispersion
In this paper, several aspects of the turbulent relative particle dispersion are considered, many of which are motivated by laboratory experiment and numerical simulation results. These are, * spatial intermittency effects, (a) reduction of relative particle dispersion in 3D; (b) prevalence of power-law scaling of relative particle dispersion in 2D enstrophy cascade; * quasi-geostrophic aspects...
متن کاملRole of Electrostatic Precipitator in Industry
Electrostatic Precipitators (ESP) are most important device used to control the pollution by collecting dust particles present on flue gases. In power plants, Coal used in Indian thermal power stations is of inferior grade, at power plant flue gas is often treated with a series of chemical process and scrubbers, having low calorific value (3500-4500)kcal/kg and high ash content due to drift ori...
