Noise Reduction

For some applications, quiet operation is important. Hydraulic machines generate noise via blade wakes and shed vortices as a result of cavitation. Reducing this noise begins with an in-depth understanding of the flow; it also involves quickly testing a variety of concepts for improving flow quality and range of operation.

ANSYS tools provide the efficiency, accuracy and breadth of physics required to evaluate such sophisticated phenomena.
