CFD simulation of stirred tanks: Comparison of turbulence models. Part I: Radial flow impellers

Abstract: A critical review of the published literature regarding the computational fluid dynamics (CFD) modelling of single-phase turbulent flow in stirred tank reactors is presented. In this part of review, CFD simulations of radial flow impellers (mainly disc turbine (DT)) in a fully baffled vessel operating in a turbulent regime have been presented. Simulated results obtained with different impeller modelling approaches (impeller boundary condition, multiple reference frame, computational snap shot and the sliding m… Show more

“…Such turbulence models, as standard k−ε model, RNG k−ε model, the Reynolds stress model and large eddy simulation are well studied for homogeneous liquids (Joshi et al [24]). However, when using turbulence models inherent in dispersed systems simplifying assumptions could describe accurately the influential aspects of the flow (Hakansson et al [25]).…”

“…Los tanques agitadores son comunes e importantes para diferentes aplicaciones industriales tales como: petroquímica, farmacéutica, biotecnología, minera entre otros (Qingbai y Gance, 2010;Joshi et al, 2011;Yapici, et al, 2008) El proceso de agitación en el presente caso se refiere a forzar el fluido por medios mecánicos (eje e impulsor) a moverse de forma circulatoria alrededor del eje del tanque. El movimiento circulatorio del fluido impacta sobre deflectores que están dentro del tanque generando una disminución del tamaño del remolino y mejorando la eficiencia en la agitación del fluido.…”

“…En particular, los impulsores tipo hydrofoil son de especial interés por ser los de menor consumo de energía en la aplicación de la suspensión de sólidos (Spogys y Nunhez, 2016;Harnby et al, 2000). Sin embargo, la mayoría de los estudios de agitadores realizados mediante CFD se han enfocado en el modelamiento de flujos generados por dos tipos de impulsores, Rushton y PBT (Pitched blade turbines), muchos de ellos con agua como fluido de operación (Joshi et al, 2011).…”

“…But even in this field steady progress is observed. In computational fluid dynamics (CFD) are used models with varying levels of complexity (Joshi et al, 2011a, Joshi et al, 2011b, Gillissen and Van den Akker, 2012. There is also commercial software (eg.…”
