Abstract: There has been recently an intense interest in verification and validation of large-scale simulations and in quantifying uncertainty, and several workshops have been organized to address this ...

Abstract: After more than 30 years of intense research on large-eddy simulations (LES) of turbulent flows based on eddy-viscosity subfilter models, 1, there is now consensus that such an approach is ...

Abstract: We present a new implementation of the spectral vanishing viscosity method appropriate for alternative formulations of large-eddy simulations. We first review the method and subsequently present ...

Abstract: Gas microflows are encountered in many applications of Micro-Electro-Mechanical Systems (MEMS). Computational modeling and simulation can provide an effective predictive capability for heat and ...

Abstract: We present a generalized polynomial chaos algorithm to model the input uncertainty and its propagation in flow-structure interactions. The stochastic input is represented spectrally by employing ...
