Flow Behavior Simulation with Computational Fluid Dynamics in Spray Tower Scrubber
Majid Bayatian, Mohammad Reza Ashouri, and Rouhallah Mahmoudkhani
Abstract—Computational Fluid Dynamics (CFD) uses
numerical methods and algorithms to solve and analyze
problems that involve fluid flows. This paper describes the
application of a commercial CFD code, to Simulation of Flow
Behavior within Spray Tower Scrubber, focusing on silica
particles. First a ventilation system was designed and
constructed for pilot study. It was designed according to
velocity pressure method balanced system design stated by
VS-15-01 recommendation offered by ACGIH. Fluent package
of Ansys, Inc is used to model and simulate this problem.
Efficiency of inhalable pollutant particle collection has
increased (P–Value < 0.05) with the increase of the flow rate.
Also, with increase in the flow rate, collection efficiency of
particles was increases (P–Value< 0.05). From the simulation
experimentations, the residuals do a very good job of
converging at approximately 2460 iterations at inlet velocities of
11.176 m/s. In general, the CFD simulation can improve
efficiency, reduce cost, and shorten experimental periods. It can
also provide insights for optimal equipment design. With the
increase of water flow rate the collection efficiency of inhalable
and non-inhalable particles of silica particles increases. This is
due to the increase of surface contact of water droplets with
pollutant, which has caused the efficiency of the system. Future
work should focuses on an improved prediction of droplet size
distribution in order to enhance dust-capturing calculation.
