| 摘 要： | 为提高TEACO2激光器放电区气流分布均匀性,解决手工计算方法无法对复杂流场进行全面准确分析的问题,采用计算流体动力学（CFD）方法,应用Fluent软件对激光器主机流场进行计算模拟,分析确定了影响因素。通过对流场进行优化改进,使放电区气流分布不均匀度纵向由8.3%降低到5.2%,横向由2.3%降低到0.78%,从而使激光器稳定放电重复频率由330Hz提高到405Hz。

| Abstract: | In order to improve the airflow uniformity in discharge zone of TEA CO2 Lasers, and solve the problem that manual calculation can not analysis on complicated flow field comprehensively and accurately, it ascertains the influencing factor by Fluent software, using the method of computational fluid dynamics (CFD) to simulate the main frame flow field of the laser. Through optimizing and improving the flow field, the nonuniformity of airflow in discharge zone longitudinally decreases from 8.3% to 5.2%, and tra... |
