| Abstract | ||
| Two-dimensional aerodynamic coaxial flow chamber models are analized and compared with experimental results. Flow patterns, pressure and velocity profiles, jet entrainment and velocity fluctuations are experimentally investigated. Flow patterns are visualized by the tracer method. Two-dimensional mathematical models of coaxial flow type furnace are examined and aerodynamic characteristics are investigated analytically as well as experimentally. The flow entrainment in the jet mixing zone is investigated. The flow pattern is compared with that of the corresponding plane models, Numerical calculations using upwind-differencing iterative technique are carried out to determine the flow field behaviour. The computed results are found to be in fair agreement with the experimental measurements. | ||
