Abstract
In this work, the effects of different drag laws regarding the ice crystal impingement on the fuselage of a regional aircraft are investigated. Different probes are considered on the surface of interest and simulated like simple segments normal to the fuselage. Along each of these instrumentations, the collection efficiency has been calculated by using a RANS structured solver named UZEN and an Eulerian impingement code IMP3D, both developed internally at CIRA. The solvers are parallelized and well-assessed. The computational grid has been generated with ICEM CFD. Results show the strong influence of the shape considered for the ice crystal particles and how different laws can guide different water concentrations on the probe surface.
