Abstract: An aircraft engine is a complex structure for which some components can come into contact at high speed. Modeling this behavior is very complex as multiple physics must be considered. State-of-the-art methodologies usually ...

Abstract: Turbomachinery rotor–stator unilateral contact induced interactions play a growing role in lifecycle analysis and thus motivate the use of accurate numerical prediction tools. Recent literature confirmed by ongoing in-house ...

Abstract: In turbomachinery, it is well known that tighter operating clearances improve the efficiency. However, this leads to unwanted potential unilateral and frictional contact occurrences between the rotating (blades) and ...

Abstract: Due to an increasing need for efficiency of turbo-engines, rotor–stator clearances are being lowered. Therefore, new designs show higher probability for contacts between rotors and casings. When contacts occur, high dynamic ...
