A comprehensive analysis of turbulent boundary layer at air blowing through a microperforated surface

Current state and prospects of researches on the control of turbulent boundary layer by air blowing

“…Indeed, the growth of the turbulent shear stress with increasing mass flow rate was also observed in Ref. [101]. Admittedly, no full agreement with data [53] concerning shift of the maximum in the value u υ ′ ′ from the wall has been found.…”

“…In this case, the working part should envelop not only the perforated sample itself, but also the broad area of the flat plate around the surface, because, as is shown in Refs. [70,[76][77][78]100,101], the area of blowing effect downstream is very significant.…”

“…13 which shows the distribution of the local value of the skin friction coefficient C f over the flat plate length at the blowing coefficient C b equal to 0.00278 (2C b /C f0 ¼1.76) [101]. (The leading and trailing boundaries of the perforated sample are shown with vertical dashed lines).…”
