3D Geometry Modeling for the Entire Flow Passage of Francis Turbine with Long and Short Blades Based on Pro/E

Based on the good function for 3D modeling of Pro/E software, 3D geometry modeling for the entire flow passage of HLA351 which is the Francis turbine with long and short blades was realized by means of a series of methods of drawing from inside to outside, drawing from top to bottom, drawing lines from points, drawing surfaces from lines, and finally getting body from surfaces, so as to provide a reliable foundation for the future CFD calculation and performance prediction.
