Airfoil transonic flow buffet calculations using the OVERFLOW 2 flow solver


Journal Article

An investigation of modeling unsteady transonic buffeting flow for the NACA 0012 airfoil when using the NASA OVERFLOW 2 flow solver code is presented. For a fixed freestream Mach number and Reynolds number, buffeting flow is modeled for various angles-of-attack. The flow model is based on the unsteady Reynolds averaged Navier-Stokes equations, and three different turbulence models are considered as well as four different numerical flux functions and four different numerical limiter options. It is shown that the computed buffet response is very sensitive to details of the computational model. Copyright © 2011 by Jeffrey P. Thomas and Earl H. Dowell.
