Model Reduction Techniques for Chemical Mechanisms

摘要: To be able tomeet the increasing demands for efficiency in energy producing systems (engines, turbines and furnaces), changes geometry of combustion devices or fuel composition are necessary. Such should based on a thorough understanding both physical chemical processes involved. Today, computer simulations one most important tools research to address these issues. This is increasingly employed testing characterizing many features process, along with sometimes replacing considerably more expensive experiments. Numerous types reliable software available car engines, gas turbines, heaters boilers. However, limitation using degree which forced rely capacity. Since cases involve turbulent numerous reactions, this can serious drawback if wishes carry out detailed simulation. Codes flow situations developed account motion between small regions, often called cells, where within cell assumed homogenous. deal complex interaction reactive systems, it necessary find methods that simplify modeling such way becomes comprehensible practically useful.
