Buchaufsatz / Kapitel / Fach: Maschinenbau
The simulation of turbulent flames is still a very challenging problem due to the strong coupling of chemical kinetics, turbulent transport and flow. Improvement of the existing underlying mathematical models is guided by a validation based on experimental results. This paper reports calculations and measurements of an axisymmetric 2-dimensional premixed flame. Measurements of the flame are performed using Raman/Rayleigh laser spectroscopy. The calculations are based on the solution of the transport equation for the joint probability density function of velocity and scalars. It is shown that the quality of the results depends crucially on the quality of the underlying mixing models.
