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.
