Enabling 3D Coupled Battery Simulations With CONVERGE CFD Software

March 13, 2024 10:30 AM – 11:30 AM CDT

Presented by:

Kislaya Srivastava, Senior Research Engineer
Convergent Science

In this webinar, we will discuss the 3D modeling capabilities available in CONVERGE CFD software for battery applications. We will showcase coupled fluid-solid conjugate heat transfer (CHT) solutions to study battery thermal management. These CHT simulations can incorporate a wide array of battery models, from simplistic equivalent circuit and localized short-circuit models to more detailed electric potential solutions with electrochemistry. By coupling the SAGE detailed chemistry solver with battery simulations, we will model the complex problem of battery thermal runaway and associated vent gas generation. Finally, we will present modeling approaches for other relevant physics, including Lagrangian particle modeling for battery vent ejecta, solidification/melting models for phase-change materials, and fluid-structure interaction modeling for battery swelling via coupled simulations with the Abaqus FEA solver.
