Hydrodynamic characterization of bubble column using Dynamical High Order Decomposition approach
Year: 2023
Type: preprint
Abstract: Bubble columns are present in several applications, such as chemical and biochemical reactors and petrochemical and environmental engineering industries. This variety of applications is why understanding the bubble columns' dynamics is essential. This paper aims to describe a 2D bubble column system by a data-driven method to comprehend its dynamics better. We provided a set of simulations considering different superficial velocities to produce training data. With this data set, we compared two approaches: the Fast Fourier transformation (FFT) and the High-Order Dynamic Mode Decomposition (HODMD). Our results showed that FFT could not adequately describe the system as it has been done for a long time in the industry. However, with a few measurement points, HODMD can well represent and reconstruct the dynamics of this complex dispersed multiphase flow system.
