摘要
轴向扩散模型是非理想流动的主要模型，它对于一级不可逆反应具有解析解，而对于其它反应只有数值解，而且计算过程较为复杂，限制了该模型的使用。文章给出了轴向扩散模型的近似计算法，轴向扩散模型的计算过程大大被简化。计算结果同数值解相比，相对误差小于３％。
The axial dispersion model is main model of the imperfect fluid. It has a analytical answer for the first order irreversible reaction.But for the others reaction,it only has numerical answer.The use of the model is limited because of the complexity of the process of the calculation.This paper gives a method of approximation for the axial dispersion model.The calculations involved in axial dispersion model can be much simplifield.Compared with the numerical solution,the relative error are less than 3%.
