Nonintrusive Stabilization of Reduced Order Models for Uncertainty Quantification of Time-Dependent Convection-Dominated Flows
M. Gunzburger, T. Iliescu, M. Mohebujjaman +1
In this paper, we propose a nonintrusive filter-based stabilization of reduced order models (ROMs) for uncertainty quantification (UQ) of the time-dependent Navier-Stokes equations…
Commutation Error in Reduced Order Modeling of Fluid Flows
Birgul Koc, Muhammad Mohebujjaman, Changhong Mou +1
For reduced order models (ROMs) of fluid flows, we investigate theoretically and computationally whether differentiation and ROM spatial filtering commute, i.e., whether the commut…
Physically-Constrained Data-Driven, Filtered Reduced Order Modeling of Fluid Flows
M. Mohebujjaman, L. G. Rebholz, T. Iliescu
In our earlier work, we proposed a data-driven filtered reduced order model (DDF-ROM) framework for the numerical simulation of fluid flows, which can be formally written as \begin…
Second order ensemble simulation for MHD flow in Elsässer variable with noisy input data
Muhammad Mohebujjaman
We propose, analyze and test a fully discrete, efficient second-order algorithm for computing flow ensembles average of viscous, incompressible, and time-dependent magnetohydrodyna…
