| 摘 要： | 使用ANSYS软件对行波管电子枪阴极组件进行了热分析和结构分析，计算了阴极组件的简化模型的温度和热形变。同时将热分析结果引入行波管设计软件TWTCAD中计算热形变前后电子束的射程、注腰半径、导流系数和面积压缩比的变化，使TWTCAD的计算结果与实验值更为接近。热形变导致电子束各项指标的变化对实际行波管的设计有参考价值。

| Abstract: | The flowfield of hypersonic low temperature(HYLTE)nozzle in continuous wave DF/HF chemical lasers was visualized by laser induced iodine fluorescence(LIIF) and simulated by the CFD software FLUENT. The results from the two methods were compared and basically accord with each other. In the condition given in the article, the oxidant flow was drilled by the fuel. It was compressed first and expanded later.The two streams mixed enough at the plane 10m away from the exit plane. The experimental results show that the direction of the fuel stream changed slightly while the simulative result indicated that the fuel stream flowed almost along the x axis. |
