Reducing the formation of soot in the engine can help control the cost of necessary aftertreatment components such as Particulate Filters.
Soot formation occurs when fuels don't fully combust, and
studies show that soot particles smaller than 100 nanometers are linked to a wide variety of serious health effects. Until now, in-cylinder combustion simulation approaches relied on the use of relatively simple soot chemical models and have failed to provide the accuracy in trend prediction needed to enable their use as predictive design tools. More accurate soot chemical models are available today and their use is possible in tools such as Reaction Design's FORTÉ CFD Package.
Obtaining truly predictive estimates for particle size and number density requires improvement in both the fundamental understanding of soot chemistry and of the development of accurate soot chemical models. Reaction Design has been working proactively to develop soot modeling approaches that can help reduce these harmful emissions, as we anticipate that more regulations will follow with increasingly strict limits on particle size and number.
In this seminar we will demonstrate how to use FORTÉ to simulate diesel combustion with predictions of emissions such as NOx, CO and Unburned Hydrocarbons (UHC). We will also use Reaction Design's industry leading multi-component diesel fuel model that can determine where soot is formed in the engine under Low Temperature Conditions (LTC). This fuel model can be used to investigate the impact of different fuels, operating conditions and engine designs on soot formation. Information on soot particle size through the engine cycle is also provided. We will also demonstrate how easy it is to setup an engine case and view your results in FORTÉ.
