Abstract
A numerical method for the computation of turbulent gas flow fields in a two-dimensional channel using hydrogen-air as a fuel and oxidizer with detailed reaction mechanism was developed in this paper. Because of the important role of hydrogen in the fuel and energy sectors and rapid progress of computation techniques, it is essential and wise to use the numerical calculation method to predict the flow structure and combustion performance of such complex reaction systems. Besides dealing with the theoretical basis and computation procedure, the different solution methods, such as method of minimization of Gibbs free energy and method of finite reaction rate, were treated. Though the paper is chiefly involved in discussing the hydrogen-air turbulent combustion system, the method suggested may also be applied to the calculation of flow fields with or without chemical reaction.
