Abstract

For improving the wall shear stress measurement in a fluid stream, a new procedure for calibration of the “triangular probe” is developed. This new procedure allows to have thinner probes, completely submerged into the viscous sublayer, thus it is less intrusive and reduces the experimental perturbations. Comparisons to numerical results on an airfoil surface confirm the validity of this new procedure
