The main objective of the TFAST project is to study the effect of laminar-turbulent transition location on the structure of interaction. The main question is how close the induced transition may be to the shock wave while still maintaining a typical turbulent character of interaction.

The main study cases – shock waves on wings/profiles, turbine and compressor blades and supersonic intake flows – will help to answer open questions posed by the aeronautics industry and to tackle more complex applications. In addition to basic flow configurations, transition control methods (stream-wise vortex generators and electro-hydrodynamic actuators) will be investigated for controlling transition location, interaction induced separation and inherent flow unsteadiness. TFAST for the first time will provide a characterization and selection of appropriate flow control methods for transition induction as well as physical models of these devices.


Institute of Aviation is involved in the following areas of investigations:

  • Numerical simulation of laminar-turbulent transition and investigations of its influence on basic aerodynamic characteristics of laminar airfoil
  • Modelling of Vortex Generators in numerical simulation of boundary layer transition
