| Abstract: | The two-dimensional, compressible, mass-averaged Navier-Stokes equations are used to investigate flows about a typical circulation
control airfoil. The governing equations are solved using the implicit approximate-factorization algorithm of Beam-Warming
with a modified algebraic eddy viscosity model. Results are compared with experimental data, and excellent agreement is obtained.
The effects of different jet momentum coefficients and angles of attack on the flow are studied. The mechanism of genenating
large lift by circulation control is discussed. |
