Experimental and theoretical investigations on coaxial and on turbulent free jet diffusion flames
Technical Report

OSTI ID:5178675
Numerical calculations of time mean values of temperature, velocity, and chemical species in a free jet hydrogen-flame and a coaxial hydrogen-air-flame are compared with measurements. Simple algebraic relations are used for the turbulent transport. The molecular unmixedness is taken into account by the concentration fluctuations. Furthermore the influence of combustion on the kinetic energy distribution is studied numerically by the according transport equation. The result is compared qualitatively to measurements.
