Abstract

The Squire-Young formula is widely used to calculate profile drag in two-dimensional airfoil analyses. Although experience shows that the formula provides reasonable and accurate predictions, full-Navier-Stokes CFD allows for a validation of the formula. A method is presented for evaluating the Squire-Young formula from a CFD solution and is demonstrated for several airfoils, including one operating in the transonic regime. Good agreement is shown between profile-drag coefficients determined using the Squire-Young formula and those calculated directly from the CFD solution using surface integration. A derivation of the Squire-Young formula is also included to aid in understanding the influence of its assumptions on its predictions.
