Hi,
i would just like to clarify some terms used in aerodynamics with you guys here and find out more about these terms at the same time.
Turbulent shear layer: Does this term refer to the first layer of air immediately adjacent to the wall surface over which the air flows? Turbulent eddies here would have a very small length scale as compared to the solid surface? How is this layer different from/related to turbulent boundary layer and turbulent wake?
From my understanding, turbulent wake is simply the turbulence downstream of the airfoil, generated by perhaps vortex shedding at the trailing edge.
Turbulent boundary layer is simply the layer of airflow over the surface where the turbulent shear layer is a part of.
Also, what are the different acoustic characteristics generated by each of these entities?
thank you!
