CFD Investigation of Hydrodynamics in an Industrial Suspension Polymerization Mixing Reactor

Investigation of Surfactant Effect on the Operational Characteristics of a Packed Bed Internal Loop Airlift Reactor

Investigation of turbulency on the rate of induced liquid circulation, gas hold-up, mixing time and overall gas–liquid volumetric oxygen mass transfer coefficient. The various types of surfactants (containing Brij58, TritonX-405, Tween40, HCTBr) with various concentrations of 1-5 ppm were examined on the operational characteristics of the reactor. In surfactant solutions (in comparison with pur...
