Turbulence intensity of the incoming wake shifts the onset location of transition upstream. Measured velocity profiles are coincident with families generated by the modified wall law in the range up to y + = 40.
#BOUNDARY LAYER AIRFOIL SKIN#
Variations of the skin friction are quite similar to that of the flat plate boundary layer in the uniform turbulent inflow of high intensity. To measure skin friction coefficient identifying the transition onset and completion, an extended wall law is devised to accommodate transitional flows with pressure gradient and nonuniform inflows. Reynolds number based on the airfoil chord varies from 2.0 × 10 5 to 6.0 × 10 5 distance between two airfoils varies from 0.25 to 1.0 of the chord length. The airfoil is installed in the incoming wake generated by an airfoil aligned in tandem with zero angle of attack. Transition characteristics of a boundary layer on a NACA0012 airfoil are investigated by measuring unsteady velocity using hot wire anemometry.
