A Hierarchical Approach for the Simulation of Reactive Thermofluidic Processes in IC Engines
Abstract: Engine combustion processes exhibit increasing complexity as industry strives to cope with strict emission regulations including greenhouse gases. Fundamental understanding of underlying reactive thermofluidics becomes a priority, but depending on the application at hand, quite different modeling and experimental methods are required for design and optimization.
In this talk, we will examine an example of an established, but still insufficiently understood technology (pre-chamber induced combustion in gas engines), how simulation methods from RANS through LES to DNS can be used together with targeted experiments to improve our understanding of key flow-thermochemistry interactions. Making such a synergetic approach work is, however,quite challenging so that application of the concept is still in its infancy.
Bio: Konstantinos Boulouchos is a professor and head of the Aerothermochemistry and Combustion Systems Laboratory at the Swiss Federal Institute of Technology (ETH) Zürich. His research focuses on reactive thermofluidics in internal combustion engines, both experimentally and computationally. In particular he is interested in interfacing insights from fundamental combustion research with industrial applications toward potentially "zero-emission" unsteady combustion systems.
