The regenerative turbomachine was investigated as a pressure-increasing device, using both air and water as working fluids. Three machines were involved, representing two geometries. A non-dimensional correlation was developed, relating pressure and flow to driving torque. This was confirmed by experiments, using data from widely separated investigations. This information was used to prepare a study of maximum efficiency as a function of specific speed. A single loss coefficient was found to be the governing parameter.
