Abstract
An algebraic eddy viscosity model, based on a new length scale has been developed. The model proposes the eddy viscosity as a solution of a quartic (Q4) equation. The turbulent length scale for attached and separated flows is defined by employing a vorticity function F = yΩD introduced in the Baldwin-Lomax model. The algebraic-Q4 eddy viscosity model was incorporated into Navier-Stokes code and tested for complex transonic airfoil flows with separation. The results are compared with the experimental data.
