CONVERGE CFD software offers a full suite of tools to model engine-out emissions reduction in aftertreatment systems. CONVERGE allows users to conduct uniformity studies, model surface chemistry reactions in catalysts such as SCR, DOC, and LNT, and predict the pressure drop and soot filtration performance of diesel and gasoline particulate filters. Additionally, CONVERGE offers cutting-edge tools for modeling urea deposits in urea/SCR systems. The urea detailed decomposition model, coupled with the deposit solidification model and surface deformation feature, enables more accurate predictions of urea deposit buildup. Simulation acceleration schemes, namely the fixed flow and combined parcel features, allow a faster turnaround time for film and urea deposit simulations. In this webinar, we’ll demonstrate how you can apply these models to evaluate and optimize the performance of aftertreatment systems.
