Temperature sensitive paint images from a wind tunnel campaign for the CRM-NLF geometry are used to extract experimental transition lines to be used to determine critical N-factors based on incompressible and compressible linearstability theory. Based on the eN-method, transition locations are subsequently predicted for different flow conditions using RANS computations and the results are compared to the experiment.
