Mean boundary layer
WebApr 27, 2024 · Numerical computations are performed to investigate the potential for transition control in an axisymmetric boundary layer via fully realizable, streamwise stationary streaks induced by an azimuthally periodic array of surface mounted vortex generators (VGs). Previous work has shown that suitable streaks of this type can … WebThe region of fluid flow with the temperature gradient is called the thermal boundary layer. The thickness of the thermal boundary layer, ઠₜ, is the distance from the surface boundary to the point where the temperature of the flow has reached 99% as …
