A variational multiscale framework for non-Newtonian fluid models
… implementations. In this dissertation, the Variational Multiscale (VMS) framework is employed to derive stabilized mixed formulations for advection-diffusion, shear-rate dependent, viscoelastic, and shear-rate dependent viscoelastic fluid models. The VMS framework leads to a two-level …

Numerical Analysis for Data-Driven Reduced Order Model Closures
… Thus, we propose a new ROM, the data-driven variational multiscale ROM (DD-VMS-ROM) built by adding a closure term to the G-ROM, aiming to increase the numerical accuracy of the ROM approximation without decreasing the computational efficiency. The closure term is constructed based on the …

A variational multiscale computational framework for nonlinear interfacial solid mechanics
This dissertation develops a robust computational framework for solving solid mechanics problems containing strong or weak discontinuities arising from interfaces. The framework consists of a stabilized version of the Discontinuous Galerkin method to handle interfaces combined with a stabilized …
