CFD Simulation of Wet Scrubbers Part 1. Principles and Implementation into Commercial CFD Software

Abstract

CFD Simulation of Wet Scrubbers Part 1. Principles and Implementation into Commercial CFD SoftwareThe design and optimization of wet scrubbers solely based on laboratory experiments is a challenging task. In addition to laboratory experiments, CFD tools for wet scrubber simulation can improve the overall performance of wet scrubbers and reduce development efforts. Subroutines to map wet scrubbers into ANSYS CFX workbench are presented. The calculation of particle capture by individual water droplets is the major feature of the implementation. The simulated specific cleaning volumes of individual water droplets show a good agreement with values found in the literature within simple geometries.

Adaptive neuro-fuzzy control of wet scrubbing process

“…(6) where p is the packing density, gl is the viscosity ratio of water to air.J d is the diffusion flux given by (7), R p is the interception parameter given by (8) and K d is the diffusion parameter described by (9).…”

“…Hence, several attempts have been made to improve the process such as in [4], [5], [6], [7], and [8] respectively. Other studies involved the application of computational fluid dynamics (CFD) such as in [9], [10] and [11]. Most of the studies provided only analytical solutions for the performance of the scrubber system while others are more complex and require intensive computation.…”
