REDAWN project will foster the adoption of hydropower energy recovery technology in built water networks in the Atlantic Area (AA). REDAWN will develop an adequate institutional, social and technological environment to foster greater resource efficiency in water networks. Pumps working as turbines (PAT) and other converters (wheels) became attractive to improve the water sector energy efficiency. However, the behavior of these devices are complex and it is difficult know its behavior. To overcome this problem, computational fluid dynamics (CFD) models were used in conjunction with the conceptualization and laboratory tests to explore its performance. Different modes were tested and simulated: single PAT mode and in parallel in pressurized pipe systems and a wheel in an open channel flow.
