The main research interests of Andreas Dreizler are focused on a fundamental understanding of turbulent combustion and advanced combustion diagnostics. The approach taken to improve the understanding of combustion phenomena such as turbulence-chemistry interactions, flame-wall interactions, stratified combustion, flame propagation, or ignition phenomena is based on a hierarchy of experimental benchmark flame configurations of rising complexity. This sequence of investigations span from atmospheric jet or opposed jet flames, over swirling flames, to enclosed and intermittent combustion as in gas turbine combustors or IC engines. Common to all of these configurations is the knowledge or as best as possible control of inlet and boundary conditions. This is a prerequisite for close collaboration with researchers from numerical combustion who take advantage of these comprehensive data for the purpose of validation. Using advanced optical diagnostics most important flow and scalar field features are investigated in detail. New diagnostic methods are adapted or even developed in case there is an urgent need.
There are strong international ties with a large number of groups, experimental and numerical. The work has been awarded by several prizes and invitations to plenary lectures. Andreas Dreizler authored and coauthored more than 140 archival journal publications.
