Systematic and logical similarity analyses of the flow, mixing and combustion were conducted based on the fundamental conservation equations of mass, momentum, species and energy, and boundary conditions that govern their phenomena. The dominating dimensionless parameters were derived for discussing the similarity law of the flow, mixing and combustion in turbulent flow field based on the assumption that the turbulence is strong enough and the influence of laminar transport can be entirely neglected. Therefore, the k-ε two equations turbulence model and the transport equations for k and ε were taken into consideration when deriving the dominating parameters. And, also the turbulent reaction model was incorporated when the dominating parameters for the turbulent jet flames were derived. Some examples are show of the similarity of non-reacting turbulent jets and turbulent jet flames. Their dominating parameters of the flame height of turbulent jet flames are also discussed.
