[HTML][HTML] On closures for reduced order models—A spectrum of first-principle to machine-learned avenues
For over a century, reduced order models (ROMs) have been a fundamental discipline of
theoretical fluid mechanics. Early examples include Galerkin models inspired by the Orr …

An energy-based lengthscale for reduced order models of turbulent flows
In this paper, we propose a novel reduced order model (ROM) lengthscale that is
constructed by using energy distribution arguments. The new energy-based ROM …

Pressure data-driven variational multiscale reduced order models
In this paper, we develop data-driven closure/correction terms to increase the pressure and
velocity accuracy of reduced order models (ROMs) for fluid flows. Specifically, we propose …
