“…In literature, numerous studies have been devoted to understanding the heat transfer in bubble columns using simple systems, like air-water [10][11][12][13] in absence of chemical reaction. The present work, however, shows a different approach.…”

“…Also, bubble size governs the gas hold-up and the interfacial area, which influences the gas-liquid mass transfer rate. Numerous studies have used CFD for studying bubble flow patterns and internal hydrodynamics of bubble columns [17][18][19][20][21]. In each of these cases, high fidelity models are required to obtain accurate predictions of axial velocity and eddy diffusivity, particularly near the wall, in order to understand the gas-liquid flow pattern and pressure drop inside the bubble column.…”

“…Bubble drag coefficient is predicted because drag force formulation is significant in describing regime transitions [20]. According to Dhotre et al [21], knowledge of the heat transfer coefficient between cooling or heating surfaces and the gas-liquid dispersed bed is required for designing bubble columns. It is important to understand the effect of superficial gas velocity on the heat transfer coefficient.…”

This research investigates the effects of the sparger on flow patterns and heat transfer within a column photobioreactor (PBR) using computational fluid dynamics (CFD). This study compares two types of spargers: a porous membrane, which occupies the entire floor of the reactor, and a single sparger, which is located along the centerline of the PBR floor. The PBR is modeled using the Lagrangian-Eulerian approach. The objective of this research is to predict the performance of PBRs using CFD models, which can be used to improve the design of PBRs used to grow microalgae that are used to produce biofuels and bioproducts.

“…Usually bubble columns operate either in a bubbly flow (homogeneous) regime or churn-turbulent flow (heterogeneous) regime depending on the phases physical properties, operating conditions and the system flow characteristics (Shaikh and Al-Dahhan, 2007). Recently, in many of the commercial installation and industrial applications of bubble columns the churn-turbulent flow regime has been found of considerable and practical interest (Dhotre et al, 2005). In churn-turbulent flow regime high gas throughout is used which yields higher volumetric productivity.…”
