Point by point method centrifugal impeller design

POINT BY POINT METHOD CENTRIFUGAL IMPELLER DESIGN SERIES

The shape of the blade is obtained from a numerical solution of the meridian flow net the on meridional plane and blade mean camber lines on stream-surfaces of revolution. In this design method, the flow field of the impeller is computed with the hypothesis of multiphase homogeneous flow on the basis that it is the practical flow regime in the multiphase pump. The three-dimensional blade design method is adopted to design the blades of the impeller of a helico-axial multiphase pump.

POINT BY POINT METHOD CENTRIFUGAL IMPELLER DESIGN SERIES

The sheet functions from a series of assumptions based within the design experience and requires inputs regarding the desired power, fluid flow rate, and total-to-total pressure ratio, as well as inlet conditions. The tool relies on design experience presented by Aungier and BaljР“В© as well as other experience drawn from available literature. In this work, two common references for conceptual compressor design were cross-checked to develop an Excel-based tool to quickly determine the design space for a given set of compressor requirements. The authors are unaware of any tool available that bounds the range of design parameters for a centrifugal compressor stage without applying a point-by-point method. This can be done manually or through automation to optimize for a specific operating parameter, such as efficiency. While new compressor designs are a common occurrence in applied research applications, conceptual design typically require a point-by-point process to balance the requirements with acceptable design parameters. Without a previous design, it is difficult to make initial trade studies of an appropriate impeller diameter, speed, and number of compression stages. In some cases, however, a completely new design is needed because no previous designs are available for the specific operating range of interest. Journal of Verification, Validation and Uncertainty QuantificationР”В¬ommonly, compressor designs rely on previous machines that can be slightly modified to achieve new operating requirements.
