CONVERGE for Electric Motors

Room 1 | 8:00am–10:00am

This course offers a hands-on introduction to modeling flows in electric motors with CONVERGE. Participants will work through the setup of an oil-cooled motor simulation, starting with geometry creation, geometry import, boundary flagging, case setup, numerical models and parameters, case execution on HPC, and analyzing the flow and temperature field results. We will additionally discuss air-cooled and external-water-jacket-cooled devices as well as rotational jet impingement cooling. We will demonstrate different methods for treating the rotational motion of the motor, including the moving geometry approach, the simplified fixed geometry approach, and the multiple reference frame approach. Furthermore, we will explore options for coupling the heat source and/or thermal solution with external electromagnetic software packages. 

*This session includes hands-on CONVERGE Studio practice.

Advanced Topics in Internal Combustion Engine Modeling

Room 2 | 8:00am–12:00pm

In this workshop we will discuss timely and popular topics in internal combustion (IC) engine modeling and some of the unique features in CONVERGE that support accurate and efficient engine simulations. We will discuss how to leverage CONVERGE’s Adaptive Mesh Refinement and its coupled flow and detailed chemistry solvers to capture autoignition and propagating pressure waves to simulate engine knock. Furthermore, we will address how CONVERGE’s cell-based load balancing, excellent scalability, and variety of acceleration strategies lend themselves to running both multi-cycle simulations to understand cycle-to-cycle variation and multi-cylinder simulations to analyze cylinder-to-cylinder variation. Finally, we will discuss how to predict cylinder pressure with CONVERGE and talk about what to do if your predicted cylinder quantities do not match the measured data, including how to assess the accuracy of your input parameters.

*This lecture includes hands-on CONVERGE Studio practice.

CONVERGE for Battery Systems

Room 1 | 10:00am–12:00pm

This course offers a hands-on introduction to CONVERGE for battery modeling. We will discuss how to set up air- and liquid-cooled battery pack conjugate heat transfer simulations in CONVERGE to investigate battery thermal management. We will go through the different approaches available to model heat generation within the battery solid. In addition, we will cover how CONVERGE’s SAGE detailed chemistry solver can model gas-phase combustion of vent gases ejected during thermal runaway as well as solid-phase thermal runaway chemistry. We will present a variety of case studies involving thermal runaway propagation and discuss approaches to run coupled vent gas generation simulations through user-defined functions.

CONVERGE for Engine Aftertreatment Systems

Room 1 | 1:00pm–5:00pm

This course offers a hands-on introduction to CONVERGE for Urea/SCR engine aftertreatment modeling. We will discuss urea decomposition and hydrolysis to ammonia, and we will describe how to set up urea-water spray modeling in CONVERGE. In addition, we will discuss Kuhnke and Bai-Gosman wall interaction models, various phenomena that can lead to urea deposit formation (e.g., filming, rebounding, stripping, and separating), and the application of conjugate heat transfer modeling to obtain accurate wall temperatures. We will discuss aftertreatment system surface chemistry components, such as SCR, DOC, TWC, LNT, and DPF/GPF, which can be solved directly with CONVERGE or via coupling with GT-SUITE. This course will include sample cases for practical Urea/SCR systems as well as validation cases. Finally, we will discuss solution acceleration approaches, which allow CONVERGE to simulate timescales necessary for film and deposit evaluation.

CONVERGE for H2 Combustion

Room 2 | 1:00pm–5:00pm

There is extensive interest in using H2 as a fuel to power internal combustion engines (ICEs), gas turbines (GTs), and rotating detonation engines (RDEs). Several OEMs are either working on or have released prototype engines that use H2 as a fuel. H2 poses several modeling challenges for CFD, stemming from its high injection velocities, low density, high mass diffusivity in air, wide flammability range, high burning velocities, and low ignition energy. In this hands-on training session, we will show how CONVERGE is uniquely suited to address these challenges in relation to various applications, including flame flashback control in dual-fuel ICEs and GTs, lean blowout (LBO) in GTs, accurate NOx modeling, and the transition to detonation in RDEs.  

*This session includes hands-on CONVERGE Studio practice.
