Research on the influence of spanwise cross-flow on the boundary layer transition of compressor cascade

What is it about?

Various methods have been used to study the phenomenon of boundary layer transition on blade surfaces, including vortex visualization and instability analysis. The independent variables studied include angle of attack, normal position, chord position, and spanwise position. The dependent variables used as research objects include streamline, velocity, Q, kinetic energy, and disturbance amplitude. Overall, in order to summarize the influence of cross flow on transition, a comprehensive view of the boundary layer before and after transition was provided as much as possible, providing a reference for relevant basic research.
