Main topics of the research of Dr. de Lange are the boundary layer transition, heat transfer and cooling in gas turbines and the thermodynamics and transient behavior of turbine/compressor systems.The flat plate boundary layer experiments in a water channel have been performed. The particle image velocimetry (PIV) was used to analyze the coherence of flow structures in the vicinity of breakdown to turbulence.

During the presentation the following results will be presented:
a) breakdown mechanisms in bypass transition
b) the effect of local nozzle-defects on film cooling efficiency
