Patent, and then the blade-to-blade flow was computed by solving the two-dimensional steady Navier-Stokes equations, finally, overall performance and internal flowfield characterization were obtained and analyzed.2. As to radial matching between blade sections, preliminary investigations were developed from three aspects such as stall margin customizing technique, control technology of tip clearance flow, prediction model and control technology of corner separate.a On basis of reviewing on methods of achieving the goal of stall margin in design process of fan and axial-flow compressor, in conjunction of understandings on "Sweep/Dihedral", stall margin customizing technique was put forward; two-dimensional performance prediction method for stall margin customizing was developed, it can consider influences of radial stacking patterns of blade sections and axial distances between blade rows conveniently and rapidly.b A simple model for tip leakage mixing loss of unshrouded blades for compressible flow was presented.
