Abstract:

A method of simulating fluid flow through a system () having a plurality of devices (). The method includes generating a plurality of device models (), each model () corresponding to a respective device () of the system (). A set of device models is selected from the plurality of device models (). Linking information is generated for the set of device models. A fluid flow model is formed for each device () having a device model () within the set of device models. Fluid flow models are linked utilizing the linking information to form a first fluid flow aggregate system model. Fluid flow through the first fluid flow aggregate system model is simulated.

Abstract:

A centrifugal pump includes a casing containing a volute channel having a cutwater at an entrance thereof. An annular vane-island diffuser is fixed in the casing concentrically within the volute. The diffuser is arranged to be separate and discontinuous from the cutwater of the volute. An impeller rotatably mounted on a shaft is disposed concentrically within the diffuser. The diffuser can be formed, e.g., by an investment casting process, integrally with the casing, or alternatively, independently of it. By arranging the diffuser to be independent of the cutwater of the volute, the diffuser can be “clocked” or “overturned” relative to the cutwater to minimize radial loads on the cutwater and dynamic loads on its leading edge. Additional advantages of the novel design include reductions in pump weight, radial loads, friction loss, design and modeling time, and the energy of outgoing acoustic waves at the pump discharge.
