Mechanism of Mixing of Two Nonreacting Gases

摘要

The turbulence phenomena associated with the mixing of fuel and air in a supersonic combustion ramjet are studied. The turbulence generated by coaxial and normal jet fuel injection is studied by analyzing a control volume in which fuel and air are mixed. These two modes of fuel injection are examined for various initial conditions in order to compare their respective characteristics and determine the design advantages of each mode. Experimental results from a compressible turbulent shear flow experiment, the decay of a supersonic free jet, having important theoretical implications and are used in formulating a new theoretical model for turbulent shear flow.
