Méthode numérique semi-implicité et instationnaire d’interaction fluide visqueux-fluide parfait pour les écoulements décollés transsoniques. (French) Zbl 0546.76023

A new unsteady calculation method, implicit, solving transonic viscous flows with separations over airfoils is presented. Transonic calculations have been performed with the NACA 64A010 airfoil, oscillating in pitch, with shock-induced separation. Results have also been obtaind on self- induced oscillations generated by the unsteady separation over the symmetrical biconvex circular 18 % airfoil at transonic speed.
