Development of a method for geometric modeling of centrifugal compressor impellers

The practice of designing centrifugal compressors in which impellers are the main components shows that there reserves for their further improvement. One consists improving flow conditions compressed medium compressor setting and, above all, impeller. A method geometric modeling settings was proposed involves construction meridional boundaries and blade profile on an involute cylindrical surface outer radius is represented by ruled surfaces. boundary impeller described a curve natural parameterization using cubic dependence curvature arc length. Dependences length determined process based set source data. problem solved minimizing deviations intermediate curves from endpoint. inner obtained as envelope circles inscribed channel Radii taking into account areas channel. midline modeled presented with quadratic law distribution. computer code developed Fortran Power Station programming environment visualizes numerical results graphically display addition to digital information profile. Graphical were presented. They confirmed efficiency impellers. can be useful offices involved design
