Abstract

Improvements to the amplification factor transport transition modeling framework are described. A locally defined, Galilean invariant parameter serves as a local shape factor for estimating the integral boundary layer properties and linear instability growth. New correlations based on this local shape factor are presented, and the resulting Galilean invariant model is a theoretical improvement over the current state of the art in computational fluid dynamics transition modeling. Several validation cases are presented, including a zero-pressure-gradient flat plate, several airfoils, a commercial transport aircraft configuration, and a helicopter rotor in hover. The predictive capabilities of the model, including its behavior in complex flow fields, are discussed.
