The Department of Chemical Engineering at the University of Technology discussed the tagged master's thesis.

Hydrodynamics Characterization in air-lift reactor via Computational Fluid Dynamic simulation

The thesis of the student Marwa Muhammad Jassim aimed to test the ability of CFD simulation to study the hydrodynamic parameters (fluid velocity field, turbulent kinetic energy field, and gas absorption) for the air lift reactor in the two-dimensional axis and to investigate the effects of the interfacial forces that use different closures on the program predictions, as All effective forces (pull force, lift force, turbulent kinetic force) are taken into account and the numerical solution is generalized so that it can be used in the future to improve the performance of air lift reactors because these reactors are used in a wide range of industrial applications for example in the chemical and petrochemical industries and also in some Biological processes such as wastewater treatment processes. Uncertainty analysis was used to find accuracy in comparing simulation (computational) values ​​and experimental results on the graph for all parameters of the flow dynamics. CFD modeling generally provided good agreement with experimental measurements of the gas retention profile, the upward fluid velocity profile, and the kinetic energy of the turbulence and its dissipation rate.
