COMPUTATION OF A DIFFUSION FLAME IN A TRANSITIONAL FLOW RANGE

The length of diffusion flames in laminar flow regimes is directly proportional to the gas flow velocity. With increasing flow velocity, the flame becomes turbulent and the regime is transient. At high flow velocities, the flame is fully turbulent, and the length does not depend on the flow velocity. The turbulent and laminar regimes have been previously studied, but the transient regime, which involves both molecular and turbulent transfer, has not yet been thoroughly studied. In the present study, experiments in the transient regime were made with carbon monoxide and hydrogen combustion. (Author) Edited trans. of Akademiya Nauk Kazakhskoi SSR, Alma-Ata.
