Prediction of Boundary-Layer Characteristics of an Oscillating Airfoil.

Abstract

The evolution of unsteady boundary layers on oscillating airfoils is investigated by solving the governing equations by the Characteristic Box scheme. The difficulties associated with computing the first profile on a given time-line, and the velocity profiles with partial flow reversal are solved. A sample calculation has been performed for an external velocity distribution typical of those found near the leading edge of thin airfoils. The results demonstrate the viability of the calculation procedure. (Author)
