Turbulent prcmixcd combustion occurs in a wide variety of technical applications.

Turbulent prcmixcd combustion occurs in a wide variety of technical applications. As a turbulent combustion model is ultimately aimed at the design process, numerical simulations should give results in relatively fast turnover times without sacrificing physical accuracy. An initial analysis shows that the technically relevant turbulent prcmixcd combustion processes occur almost exclusively within the so-called corrugated flamclct and thin reaction zone regime. In these regimes, the relevant chemical time and length scales arc smaller than the respective turbulent time and length scales.

The model is valid in the flamelet regime, where the reaction zone thickness is smaller than the Kolmogorov length scale.

Recent models based on direct numerical simulation results correctly predict the bending'' of the turbulent burning .

Recent models based on direct numerical simulation results correctly predict the bending'' of the turbulent burning velocity U] as a function of the RMS turbulent velocity u as well as the total quenching of the flame in sufficiently intense turbulence. A stochastic simulation model of the wrinkled flamelet regime of turbulent premixed combustion is shown to exhibit several postulated scaling properties governing flame structure and propagation rate.

The density was set to . 3 kg/m3 and the viscosity was taken as . 9 e-5 Pa s. A good value of the recirculation length was obtained. In the 3rd step we solve an unsteady transport equation for the time, or ensemble, average progress variable. This is done for all possible progress variable variances ranging from 0 to . 5 for a scaled progress variable in the range 0 to 1.

This book contains a very good theoretical concepts of turbulent combustion. In particular, the use of flamelet is treated in great details. This book shows why Peters is so much regarded in combustion community. First chapter contains a good overview of present numerical approached to solve turbulent combustion problem. Till now I have covered only premixed part of the book, which I find very interesting and illuminating. Also the book cover G-equation model in very good detail. 2 people found this helpful.
