Fitting an isoefficiency curve for axial flow pump based on cubic uniform B-spline
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 2
Abstract
We introduced the Cubic uniform B-spline fitting method for isoefficiency curve of the comprehensive characteristics of the axial flow pump. Various shapes of isoefficiency curves can be achieved by setting different curve parameters according to their properties. This not only can greatly reduce the complexity of traditional method of curve fitting, but also can be used in other similarly complicated curve fitting cases.
