Interactive airfoil calculations with higher-order viscous-flow equations

Abstract

A critical examination of the use of higher-order viscous-flow equations in the computation of airfoil flowfields with a viscid-inviscid interaction scheme is presented. Comparisons are made between experimental data and interactive solutions obtained using the boundary-layer equations, the second-order boundary-layer equations, and the Navier-Stokes equations, with corresponding approximations to the viscid-inviscid matching conditions, for flows about symmetric and aft-loaded airfoils.
