General Flow Modeling (Abridged) and Engine Aftertreatment Modeling

This training session includes two courses:

General Flow Modeling In CONVERGE (Abridged) | 9AM – 1PM

This four-hour course, which is a subset of our eight-hour General Flow Modeling in CONVERGE course, offers an introduction to setting up general flow cases in CONVERGE. You will learn how to to begin a new project, import and repair a geometry, create and flag boundaries, set up your case parameters, run CONVERGE and monitor your simulation, and post-process your results in CONVERGE Studio.
 *This course is a prerequisite for Exhaust Aftertreatment Modeling and is strongly recommended if you are new to CONVERGE.

Engine Aftertreatment Modeling | 2PM – 6PM

This workshop will focus on Urea/SCR engine aftertreatment modeling in CONVERGE. 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 SCR surface chemistry, which can be solved directly with CONVERGE or via coupling with GT-SUITE. This workshop 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.
*This lecture includes hands-on CONVERGE Studio practice.
