Two-dimensional computational simulation flow of exhaust gases passing inside an electrostatic precipitator

Abstract

Abstract:In the present study the two-dimensional computational simulation flow of hot exhaust gases which are passed inside an electrostatic precipitator will be carried out. Initially, the theoretical background and necessary equations from fluid mechanics will be described. These equations will be used by software for flow simulation. Furthermore, are presented the design of precipitator through which the exhaust gases are passed. In the next step follows the declaration of various parameters of simulation on the software and finally the necessary images of the computational simulation for two case studies will be extracted. The general conclusions that arise are that the maximum flow velocity of exhaust gases prevails only at the beginning of the entrance of the precipitation element. There are different velocities in all other parts of precipitation element. When the exhaust gases approach the collecting electrodes within the element, their velocity is decreased.

Numerical Prediction of Homogeneity of Gas Flow through Perforated Plates

“…Again, a 2D CFD model was used in their investigations. Similar investigations in terms of velocity distribution in ESP were conducted by Kouropoulos [16]. Celik et al [17] in their own numerical investigations have found that porosity of the plate is the most effective design parameter in terms of pressure drop across the plate, while the least effective is the hole pattern.…”
