We have experimentally found a pumping-up mechanism, where the thin liquid film flow goes up fully upward along the outer surface of a rotating cone. The mechanism is applied to the atomization of the liquid and to the transportation of oxygen from the air to the water through the atomized water droplets. We measure the dissolved oxygen concentration and axial torque for varying the immersed radius, the total volume of water and the rotation rate. The correlation between the unit volume power consumption and the oxygen mass transfer is examined. It is found that the oxygen transfer increases in power law relationship with the unit volume power consumption. Eventually, an empirical correlation function of the oxygen mass transfer against the power consumption is obtained.
