Despite the nonlinear nature of turbulence, there is evidence that part energy-transfer mechanisms sustaining wall turbulence can be ascribed to linear processes. The different scenarios stem from stability theory and comprise exponential instabilities, neutral modes, transient growth non-normal operators, parametric instabilities temporal mean-flow variations, among others. These mechanisms, e...

The non-Hermitian skin effect is one of the most striking features in physics. It reveals a novel phenomenon system that bulk wave function and energy spectrum are sensitively dependent on boundary conditions. concept generalized Brillouin zones has been proposed to characterize functions such systems . Based zones, non-Bloch topological invariants can reconstruct bulk-edge correspondence. Prev...

The interaction between corner flow and heat transfer is very common in the internal external of hypersonic vehicle surface, but it not clear how wall thermal boundary condition affects supersonic layer. In present study, Reynolds stress model used to solve Reynolds-averaged Navier–Stokes equations. results show that when symmetrical temperature Tw less than or equal recovery Taw, mean velocity...
