Introduction to transition modelling

Abstract

With the general increase of the use and importance of CFD methods and the increased wish for highly accurate simulations, the need has grown for the availability of reliable transition prediction methods for configurations from many different application areas ranging from turbomachinery and aircraft flows to helicopters and wind turbines. On the one hand, the physical effects to be simulated, the transition mechanisms and their parameters have grow n. On the other hand, the configurations are becoming more and more complex. Thus, the availability of different transition modelling approaches serving as complementary techniques in CFD codes is highly beneficial.
