CFD Simulation for Improving Selective Catalyst Reduction (SCR) After Treatment Devices
Selective Catalytic Reduction (SCR) is widely used within industry to help meet the challenging nitric oxide emissions requirements for diesel engines. There are a number of important criteria necessary for designing an efficient SCR system, including fast mixture preparation of the liquid urea-water solution and high ammonia uniformity at the SCR device. The use of simulation to optimize the design of SCR devices is allowing engineers to improve NOx reduction, necessary for complying with aggressive emission standards. This webcast covers new modeling techniques to improve calculations and...
Academic Webcast: Modeling Multiphase Flows using STAR-CCM+
The event discusses the differences between the two categories of flow: stratified flows (e.g. free surface flows) and dispersed flows (e.g. bubbly, droplet and particle flows). Guest Lecturer, Simon Lo discusses the big differences in flow characteristics between these different types of multiphase flows and therefore the different modeling approaches that are required. STAR-CCM+ will be used to demonstrate a wide range of multiphase flow models including: Lagrangian multiphase model (LMP) Discrete Element Model (DEM) Eulerian multiphase model (EMP) Volume of Fluid (VOF) In this lecture, a...
