A Reduced-Order Model of Lithium–Sulfur Battery Discharge

Batteries
This paper examines the problem of modeling lithium–sulfur (Li-S) battery discharge dynamics. The importance of this problem stems from the attractive specific energy levels achievable by Li-S batteries, which can be particularly appealing for ...

Reduced-Order Model for Catalytic Cracking of Bio-Oil

Fluids
This work presents a one-dimensional (1D) model for simulating the behavior of an FCC riser reactor processing bio-oil. The FCC riser is modeled as a plug-flow reactor, where the bio-oil feed undergoes vaporization followed by catalytic cracking ...

An error indicator-based adaptive reduced order model for nonlinear structural mechanics -- application to high-pressure turbine blades

, 2019
The industrial application motivating this work is the fatigue computation of aircraft engines' high-pressure turbine blades. The material model involves nonlinear elastoviscoplastic behavior laws, for which the parameters depend on the temperature.
