用正交配置法研究液膜内的气液反应过程

Study on Gas-Liquid Reaction in Liquid Film Applying Orthogonal Collocation Method

用正交配置法配合恰当的方程变换求解液膜内发生典型化学反应时的液膜方程，并分析诸参数对气液反应增强因子和液膜内有关组分浓度分布的影响．同精确解相比，正交配置法的计算结果误差很小；同其它数值解的比较表明，正交配置法具有直接了当和简练的优点．

The Orthogonal Collocation(OC) Method is successfully applied in solving the set of ODEs representing the absorption with different order chemical reactions taking place in the liquid film, and the influences of some parameters on the enhancement factor and the concentration profile in the liquid film are analyzed as well. A proper transformation of original equations is performed to make the application of OC method possible. Comparisons are also made between the computation outcome of OC method and the relevant exact analytic solutions and/or other relatively precise numerical solutions. It can be seen that OC Method can provide accurate and reliable outcome and has the advantages of straightforwardness and conciseness.
