Summary on Grant Application Form
Laminar burning velocity and turbulent burn rate data are fundamental to modeling of engine combustion and explosion hazards. Existing data are sparse and inconsistent, particularly at engine combustion conditions. Inconsistencies are related to burning techniques and data extrapolation, Recently the applicants' research group have developed techniques and data extrapolation. Recently the applicants' research group have developed apparatus and flame imaging techniques for studying laminar and turbulent flame development under well controlled and widely variable condition. They have also developed reliable analytical methods for establishing stretch free laminar burning velocities and the influence of flame stretch, as well as defining turbulent burning rate in terms of turbulence spectrum influencing a developing flame kernel at any instant in its growth. It is proposed to apply these methods systematically to complete a reliable library of laminar and turbulent burn rate data for iso-octane and extend a propane and methane over a wide range of pressure, temperature, equivalence ratio and turbulence intensity. Potentially even more important is study of the development of flame instabilities and cellularity, the interaction of cellular flames with imposed turbulence and self-turbulsing flames. This may have great significance in the explosion hazards field and profound implications for the engine performance/emissions modeling.
