CFD Modeling of Continuous Stirred Tank Electrochemical Reactor

摘要

Electrochemical reactors play an important role in electrochemical industries as they directly involvein achieving higher conversion and current efficiency for the desired reaction. The continuous stirred- tank electrochemical reactor (CSTER) is extensively used in electrochemical industries for variousapplications. The flow behavior of electrolyte in a continuous stirred tank electrochemical reactor[CSTER] has been experimented using Residence Time Distribution (RTD) studies. Experiments werecarried out using pulse tracer technique and the exit age distribution curves for various operatingconditions have been critically analyzed. A two-dimensional flow model was developed to visualizethe electrolyte flow behavior inside the CSTER using Computational Fluid Dynamics (CFD).GAMBIT, Geometry and mesh generation software has been used as pre-processor and computationalgrid domain was generated with appropriate boundary conditions. Navier-Stoke equations were usedto estimate the electrolyte flow. The influence of electrolyte flow rate, stirrer speed on electrolyte flowbehavior was critically examined.
