PL05 - A FEM APPROACH TO PREDICT ACOUSTIC RESONANCE IN MULTISTAGE CENTRIFUGAL PUMP
Abstract
Acoustic resonance that can develop within the hydraulic channels of the pump, especially in the long crossover channel of a multistage, has always had in the past a minimal consideration if compared with other dynamic behaviors. A possible issue on field, not intercepted during the development phase of a new machine, has become the occasion for an improvement of the design procedure. A fundamental factor in the development of this new method is the increase in computational capacity. The design procedure moved from a simple spreadsheet where it was possible to implement a simple one-dimensional geometry to a FEM calculation that represented the real geometry in all its three-dimensional complexity and that compared with experimental tests shows the excellent predictability.
