An Evolve-Then-Correct Reduced Order Model for Hidden Fluid Dynamics

open access: yesMathematics, 2020
In this paper, we put forth an evolve-then-correct reduced order modeling approach that combines intrusive and nonintrusive models to take hidden physical processes into account.

IGBT Temperature Field Monitoring Based on Reduced-order Model

open access: yesCES Transactions on Electrical Machines and Systems, 2023
With the rapid development of the world economy, IGBT has been widely used in motor drive and electric energy conversion. In order to timely detect the fatigue damage of IGBT, it is necessary to monitor the junction temperature of IGBT.

Pressure Stabilization Strategies for a LES Filtering Reduced Order Model

open access: yesFluids, 2021
We present a stabilized POD–Galerkin reduced order method (ROM) for a Leray model. For the implementation of the model, we combine a two-step algorithm called Evolve-Filter (EF) with a computationally efficient finite volume method.

Finite element reduced order models for nonlinear vibrations of piezoelectric layered beams with applications to NEMS [PDF]

open access: yes, 2012
This article presents a finite element reduced order model for the nonlinear vibrations of piezoelectric layered beams with application to NEMS. In this model, the geometrical nonlinearities are taken into account through a von Kármán nonlinear strain ...

Identification of frame dynamics of vertically oriented high-speed steam generator using model update procedure for reduced-order model [PDF]

open access: yes, 2020
Active Magnetic Bearing (AMB) systems are common in high-speed rotating machinery. Bearing control system input is the relative displacement data measured between the sensor and the measurement surface. In case of frame resonance, controller may create a
