Projection-based model order reduction for prestressed concrete with an application to the standard section of a nuclear containment building
Eki Agouzal, Jean-Philippe Argaud, Michel Bergmann +3
We propose a projection-based model order reduction procedure for the ageing of large prestressed concrete structures. Our work is motivated by applications in the nuclear industry…
Large eddy simulation of a low-pressure turbine cascade with turbulent end wall boundary layers
Christian Morsbach, Michael Bergmann, Adem Tosun +3
We present results of implicit large eddy simulation (LES) and different Reynolds-averaged Navier-Stokes (RANS) models of the MTU 161 low pressure turbine at an exit Reynolds numbe…
A projection-based reduced-order model for parametric quasi-static nonlinear mechanics using an open-source industrial code
Eki Agouzal, Jean-Philippe Argaud, Michel Bergmann +2
We propose a projection-based model order reduction procedure for a general class of parametric quasi-static problems in nonlinear mechanics with internal variables. The methodolog…
Large eddy simulation of a low pressure turbine cascade with turbulent end wall boundary layers
Christian Morsbach, Michael Bergmann, Adem Tosun +2
We present first results of an implicit large eddy simulation of the MTU T161 low pressure turbine at a Reynolds number of 90,000 and Mach number of 0.6, both based on isentropic e…
Fluid-solid Floquet stability analysis of self-propelled heaving foils
Luis Benetti Ramos, Olivier Marquet, Michel Bergmann +1
We investigate the role of linear mechanisms in the emergence of nonlinear horizontal self-propelled states of a heaving foil in a quiescent fluid. Two states are analyzed: a perio…
Calibration of projection-based reduced-order models for unsteady compressible flows
Victor Zucatti, William R. Wolf, Michel Bergmann
An analysis of calibration for reduced-order models (ROMs) is presented in this work. The Galerkin and least-squares Petrov-Galerkin (LSPG) methods are tested on compressible flows…
