摘要

The most popular conventional combustion models are the "Eddy-Break-Up Model" by Spalding and "Eddy Dissipation Model" by Magnussen, both of which are accepted as applicable to premixed flames. However, these models have not simulated all the premixed combustion phenomena. In this paper we assess four combustion models; (1) "Eddy Dissipation Model" : "Magnussen Model" ; ( 2 ) premixed combustion model of the "Katsuki Model" which controls the reaction rate by the Damkoeh-ler number; (3) the "Kido Model", which predicts turbulent burning velocity by laminar burning velocity and turbulent characteristics and ( 4 ) the "Modified Katsuki Model", in which the fluctuations of concentrations and temperature are solved by the transport equation. In present work, the Kido model is newly presented as computational code based on the flame cell concept and the modified Katsuki model is also developed for application to multi-fuel systems. Our study showed that the "Modified Katsuki Model" could predict the premixed combustion phenomena sufficiently and could trace the changes of the frame front.
