Resolution of the Navier-Stokes equations applied to the computation of the laminar flow around a two dimensional wing profile
Abstract
A two dimensional Navier-Stokes equation computation code of the laminar flow around a wing profile is presented. The equations are discretized by finite volume method. The motion quantity equations are resolved by an alternate direction method and the pressure correction equation by the conjugate gradient method with preconditining. Results of calculations on a NACA0012 and an AS239 profile at different incidences are presented. A comparison with a boundary layer computation code is carried out.
