Numerical Simulation of Acoustic Resonance in a Duct Containing a Flat Plate

Fluids, 2022
This work is about numerical simulations of vortex induced acoustic resonance in a duct, experimentally investigated by Welsh et al. Vortex shedding of low-speed flow over a flat plate excites an acoustic duct mode, leading to a lock-in of shedding and ...

Theorie der Pfadabhängigkeit

Monitor Versorgungsforschung, 2022
Die Theorie der Pfadabhängigkeit (David 1985; Arthur 1994; Sydow et al. 2009) ist ein zentraler Ansatz, nicht zuletzt der Organisations- und Managementforschung, um die Rigidität von Organisationen, Technologien oder Systemen gegenüber Wandel zu erklären.
