WebFlow vorticity magnitude of both aerofoils, along with the spectra of the vertical fluctuating velocity component and noise level, are analysed to demonstrate the bubble flapping process near the trailing edge (TE) and the vortex shedding phenomenon. Findings. Originality/value. WebIn this method, fluctuating velocity components are computed by synthesizing a divergence-free velocity-vector field from the summation of Fourier harmonics. In ANSYS FLUENT, the number of Fourier harmonics is fixed to 100. Both the vortex method and the spectral synthesizer are available for velocity inlet and pressure inlet boundary conditions.
