Title of the articleSimulation of filtration of two-phase of aerosol with ash of power coals and ways to address the electrostatic forces
Abstract.For flow filter structure of the porous filter layer in all cases is a system of channels and obstacles. When approaching the particle to the fiber, there are several mechanisms that can result in trapping: gravitational deposition effect touch inertial capture, capture diffusion, electrostatic deposition. Between the aerosol particles and structural elements of the porous filter layer may be a electrostatic interaction, if for some reason will have electrical charges. If the filter fiber particles appear oppositely charged, there is an attraction of particles to the fibers. The mechanism of electrostatic deposition of particles can also be improved by other means including diffusion and by engagement. ANSYS CFX software module allows the calculation of steady and unsteady fluid dynamics problems. Opportunities software package ANSYS CFX do not allow to take into account the effect of electrostatic forces in the calculation. To solve this problem requires the involvement of multiple modules in series, resulting in the calculated results of one module to the next module is used as a load. The calculation of the electrostatic field to produce a module ANSYS Maxwell. To solve the problem, taking into account the influence of electrostatic forces, the flow must be represented as a two-phase flow, through which it is possible to calculate and visualize the movement of the dust. The numerical experiment was to sharpen the flow diagram of the obstacles diameter of 100 microns. Created a group of 60 injections of inert particles, defined particle properties, wondering material. The behavior of particles reaching the physical boundary may be represented by several embodiments. The behavior of particles in the set of boundary conditions for the walls and obstacles. The calculations took into account all the mechanisms of recovery with the exception of electrostatic forces. Identifies possible options and ways to incorporate electric forces in the Navier-Stokes equations.
Keywords.Electrostatic, precipitators, the numerical study, the electric field, computational fluid dynamics.
