Abstract
The decrease in power number with increasing Reynolds number sought in this thesis was observed. However, the majority of the data is not an indication of this phenomenon. Only with a relatively high ratio of turbine diameter to vessel diameter could a power number fall-off be obtained. The power number fall-off thus appears to be dependent upon this ratio of turbine diameter to vessel diameter. When the power number fall-off was evidenced, a deep vortex existed despite the presence of full baffling, and large quantities of air were entrained by the liquid.
Even after applying pseudo corrections for both entrained air and the presence of a vortex, the power number fall-off was prominent. Further work with different sizes of vessels and turbines and tip speeds is desirable.
