Zusammenfassung: | Cylindrical Split reactors are one of the types of airlift reactors that are multiphase contactors used in chemical and petrochemical applications, as well as biological processes like wastewater treatment and aerobic fermentation. The major goal of this research is to investigate the flow dynamics (hydrodynamic) features of a split airlift reactor (cylindrical shape) using these phases system by computational fluid dynamics (CFD) simulation. In this reactor, the effect of the gas holdup, fluid velocity field, turbulence kinetic energy, and its dissipation rate was explored. These parameters were detected under diverse situations, including variable liquid levels at SGV=3(cm/s), the results present that these features are shown to increase. Our other objective is to in order to accurately capture the hydrodynamics in the complex of the two-phase system, proper closure model selection is essential. Our research focuses on the impacts of interfacial forces models (such as drag, lift, and turbulent dispersion force) on local gas holdup, liquid velocity, and turbulence kinetic energy and its dissipation rate. Experimental observations of the gas hold-up profile, upwards liquid velocity profile, and kinetic energy of turbulence and its dissipation rate were all in good agreement with CFD modelling. |
