Description	Reactors with internal circulation loop are nowadays widely spread (extensively applied) in chemical industry, biochemical fermentation or biological wastewater treatment processes. Internal loop reactors consist of concentric draft tube, in which a gas bubbles rising up, and the downcomer in which the liquid is flowing downward. Size and diameter of the draft tube is of crucial importance reactor geometry parameters and together with number of the draft tubes has big effect on two phase hydrodynamics and mixing processes (mass transfer) inside the reactor. Present paper is divided onto the two parts. In the first part, the validation of selected mathematical model (mixed flow) is carried out. Results of experimental measurements (liquid velocity and gas hold-up) obtained on the laboratory scale reactor with internal circulation loop are compared with the CFD simulations. The CFD simulation (bubbly flow and mass transfer models) was made by COMSOL Multiphysics version 3.5a.
