The department has developed a wide range of codes for predicting transition, from the simpler 2D incompressible version to the 3D compressible version which was used for transonic and supersonic Laminar Flow Control applications, for example for McDonnell Douglas.

The latter offers the advantage of calculating the envelope of the neutral stability curves, called Zarf, in order to initiate amplification calculations. The code developed is efficient and extremely easy to use. It is coupled with our 3D compressible boundary layer code.
