Abstract: Abstract More powerful turbulence models than algebraic and two-equation models are of interest for the aircraft, automobile and chemical industries, to give only a few examples. The development of better models needs new concepts and the validation by complete and reliable data sets. Such a new concept is currently developed by Dr. Jovanović at TU Erlangen. His model is based on two transport equations for the second and third invariants II and III of the Reynolds stress anisotropy tensor in addition to the equations for k and ∈. This forms an important step foreward: The influence of anisotropy can be treated like in full Reynolds stress models, but the effort will be much lower.
