In a horizontal agitated thin-film evaporator, axial flow has to be induced according to the required flow rate. The axial driving force of liquid is the axial gradient of the pressure force on the cross section of the liquid fillet, and the gradient of pressure force is materialized by variation of the circumferential length of the fillet on the rotor blades. The axial driving force balances the axial component of the friction forces on the rotor and the stationary cylinder which are induced by the relative motion of liquid in the fillet and the thin film. the configuration of the liquid fillet varies depending upon the rotor speed and the flow rate as well as the viscosity of the working liquid. The relationship observed in a series of experiments was well predicted by the theory developed in this paper.
