Gas-Liquid dynamics numerical simulation of cylindrical bubble column reactors

چکیده مقاله

This paper is attempt to evaluate transient two dimensional axisymmetric simulation of cylindrical bubble column under bubbly flow and churn turbulent condition based on laboratory scale to gather experimental data, Gamma-radiation based non- invasive flow monitoring methods have been used. Also computer automated radioactive particle tracking (CARPT) application resulted in information about liquid velocity and turbulence. Gas holdup profiles have been achieved through computed tomography (CT). Numerical simulation has been performed by FLUENT software and algebraic slip mixture model findings have been compared to two-fluid Euler-Euler model. There is significant conformity between experimental data and simulation results based on time-averaged gas holdup and axial liquid velocity profiles beside to kinetic energy profiles findings show simple two- dimensional axisymmetric simulation could be used successfully to engineering calculation to overall flow and gas holdup distribution.
