The simulation of industrial aerodynamic flows
is mostly based on algebraic, one- or two-equation eddy-viscosity models (EVM).
For highly computing-time consumptive applications, such as the examination of
unsteady flow phenomena around three dimensional configurations, the one-equation
modeling framework is a viable compromise balancing computational
effort and predictive accuracy.
The paper outlines an effort to extent the predictive realms of the popular
Spalart-Allmaras (SA) one-equation model [1] towards
non-equilibrium conditions, by means of sensitizing the production term
to non-equilibrium effects.
The adopted modifications are validated for a range of engineering
turbulence-modeling applications.
