Abstract
A two-dimensional inverse method is proposed in this paper. The method can be used to design forward-swept radial and backward-swept blade profiles by means of specifying the distribution of angular momentum CuR along the mean streamline m on the stream surface of revolution of the impeller (CuR-m distribution). At the same time, the distribution of relative velocity W along the mean streamline is calculated and is used as a reference point to evaluate the quality of design. Far the impeller with backward-swept blades, the blade profiles can also be designed directly by specifying the distribution of relative velocity W along the mean streamline m (W-m distribution). Three calculated examples are presented and some advice on the choice of suitable CUR-m and W-m distributions are suggested. Results show that this design method is simple and practical, and can conveniently be combined with the designers’ experience to obtain an impeller with good performance characteristics.
