Strong coupling strategy for fluid structure interaction problems in supersonic regime via fixed point iteration

Mario Alberto Storti, Norberto Marcelo Nigro, Rodrigo Rafael Paz


In this paper we present some results on the time integration stability when solving fluid/structure interaction problems with strong coupled staged strategies. The flutter of a flat plate faced with a fluid at Mach between 1.8 and 3 is taken as a benchmark. The precision of differ- ent predictor strategies and the influence of the partitioned strong coupling on stability is discussed. [Submitted to Journal of Sound and Vibration]
