Dr. Kostiuk's general research interests are in the area of premixed turbulent combustion. Practical concerns for premixed combustion are in the efficient use of fossil fuels, formation of pollutants and the hazards from fires and explosions. Scientific concerns relate the understanding of the complex coupling that exist between fluid mechanics, thermodynamics and chemistry. His work has addressed important issues for both practical and scientific problems in combustion. Past research has been to develop models for the effect turbulence has on the burning rate and extinction of premixed flames, the dynamics and evolution of flame surfaces and effects of gravity on flames. This work has resulted in a strong interest and involvement in the associated areas of laminar combustion and non-reacting turbulent flows.

Currently Dr. Kostiuk is working with industry on the development of Low NOx, high turn-down gas fired burners. Innovative methods for controlling gas cloud explosions by water mist are being researched. Fundamental research is also continuing in the area of premixed turbulent combustion.

Key words: air pollution, combustion, fluid dynamics, natural gas, turbulence
