摘要
本文在理想吸附层假定下对两种常见的复相催化反应模型导出了反应速率表达式,分析了反应级数的变化规律和范围。采用新定义的“壁面催化非平衡系数”作为表征壁面非平衡催化工况的准参则数,用粘性激波层法计算分析了壁面非平衡催化效应对驻点区壁面热流的影响规律。
The expressions of rates of surface catalytic recombination-dissociation reaction for Langmuir-Hinshelwood and Eley-Rideal modelsare given under conditions of ideal absorption layer,and the regions ofvariation of orders for the reaction are analyzed.A“surface catalyticnonequilibrium coefficient”is defined as criterion for characterization ofnonequilibrium grade of surface catalytic reactions from“frozen regime”to“equilibrium regime”and the effects of surface nonequilibrium catalyticreactions on wall heat transfer in the stagnation region of a hypervelocityblunt body are calculated by numerical method of viscous shock layer.
