Evaluate the aerodynamic performance and structural strength of aero-engine fan blades modified with biomimetic humpback whale fin tubercles.
Generated bionic blade geometries using Python via quadratic curves governed by three control points.
Computed static aeroelastic behavior with finite element analysis and solved unsteady compressible Navier-Stokes equations using an S-A turbulence model and LU-SGS time stepping through partitioned fluid-structure coupling.
The ratio of maximum blade deformation to blade disk diameter decreased from 0.306% to 0.239%, indicating slightly increased blade strength.
Aerodynamic flow improved with a 4.09% increase in single-channel flow rate, a 4.85% rise in pressure ratio, and an increase in blade efficiency from 67.014% to 89.861% with an optimized fan seal.
Biomimetic tubercles effectively suppressed flow separation and vortex dissipation while homogenizing pressure, temperature, and Mach number distributions.
