A Method of Correcting for the Effects of the Sidewall Boundary Layer in Two-Dimensional Airfoil Testing.

Abstract

This thesis presents the results of a hydrofoil force balance design study in which the influence of sidewall boundary layers on two-dimensional force measurements is emphasized. Past problems encountered with the present hydrofoil force balance at the Applied Research Laboratory of The Pennsylvania State University are reviewed in order to provide background information for the present study and a two-phase test program designed to identify those factors associated with the presence of sidewall boundary layers which can influence two-dimensional force measurement is water tunnels and wind tunnels is presented.
