Motivation

Near wall combustion phenomena have an important impact on the efficiency and formation of unburned hydro carbons in all engine applications. This aspect is of growing interest for modern downsized internal combustion engines with increased surface-to-volume ratios. Furthermore flame wall interactions are one of the main issues in durability and lifetime of engine parts and components. These also affect the combustion chamber and turbine blades in modern gas turbines at lean combustion.

In technical applications the wall surface is much colder than the flame temperature. This can lead to an interruption of the chemical reaction, which is associated with a quenching process of the flame. The interaction of flame quenching with fluid motion, transport phenomena and chemical reaction has not been investigated and understood completely.
