Abstract
Experimental and CFD studies in a laboratory scale cylindrical bubble column under different operational conditions were performed. Axial liquid velocities were measured with the non-intrusive PIV technique. The effects of breakup and coalescence were applied with population balance method. For the interfacial forces, only drag was considering by the Zhang and Vanderheyden model. The effects of turbulence in the continuous phase were applied for the continuous phase with the k-e model. It was found that the approach used in this work provided physically consistent results, showing good agreement between the experimental and numerical data obtained for a heterogeneous flow regime.
