New Generation

In this paper, we outline the future of modelling in reaction engineering. Specifically, we use the example of particulate emission formation in internal combustion engines to demonstrate what modelling can achieve at present, and to illustrate the ultimately inevitable steps that need to be taken in order to create a new generation of engineering models.

To Come

For many decades to come, and in the foreseeable future, internal combustion engines – in many cases with electric motors – will be with us, just like the liquid fuels they require. The importance of crude oil will decline, as these fuels will be increasingly produced on a synthetic basis without CO2 emissions. The answers to the question ”Future Mobility without Internal Combustion Engines and Fuels?“ are “no” in both cases. Purely battery-electric mobility will be applied in the future only in specific areas. Fuel-cell vehicles will hardly be used because of the extreme infrastructure investment costs. In contrast, liquid fuels will ensure the future of mobility. In this scenario, energy such as solar or wind energy will be generated without CO2 emissions.

Modelling internal combustion engines can be made following different approaches, depending on the type of problem to be simulated. A diesel combustion model has been developed and implemented in a full cycle simulation of a combustion, model accounts for transient fuel spray evolution, fuel-air mixing, ignition, combustion, and soot pollutant formation. The models of turbulent combustion of diffusion flame, apply to diffusion flames, which one meets in industry, typically in the diesel engines particulate emission represents one of the most deleterious pollutants generated during diesel combustion. Stringent standards on particulate emission along with specific emphasis on size of emitted particulates have resulted in increased interest in fundamental understanding of the mechanisms of soot particulate formation and oxidation in internal combustion engines. A phenomenological numerical model which can predict the particle size distribution of the soot emitted will be very useful in explaining the above observed results and will also be of use to develop better particulate control techniques. A diesel engine chosen for simulation is a version of the Caterpillar 3406. We are interested in employing a standard finite-volume computational fluid dynamics code, KIVA3V-RELEASE2.
