Current research projects are concerned with both, premixed and diffusion (non premixed) flames, in gaseous and in multi-phase systems. In many engineering applications, such as internal combustion engines and aerospace propulsion systems, the fuel and oxidant are intimately mixed. When ignited a deflagration wave, or a premixed flame, propagates throughout the mixture. Often, however, the fuel and oxidant are initially separated and combustion occurs only when they are brought together. Non premixed combustion has also important applications; for example, in diesel engines where a spray of liquid fuel is introduced to the combustion chamber, or in fires. In studying premixed and diffusion flames, we are concerned with the description of the flame structure and its dynamics under conditions that simulate practical applications; for example in the presence of non uniform flow fields and/or confined environments.
