| 摘 要： | 介绍了等离子体微弧氧化技术(PMAO)在微型固体火箭内壁处理上的应用.采用商用CFD软件,分别对微型固体火箭燃烧室内壁经过微弧氧化处理前后的壁面温度场进行了数值仿真计算.数值仿真结果显示了生成微弧氧化层前后燃烧室壁面沿径向温度变化情况,由此分析工作过程中有无微弧氧化涂层对微型固体火箭燃烧室内壁和外壁温度的影响.结果表明,微弧氧化处理可显著提高推力器的热效率及微型固体火箭燃烧室耐高温能力.

| Abstract: | The plasma microarc oxidation(PMAO) technique was used for treating the inner wall of the combustor of solid propellant micro-rocket.The numerical simulation of the temperature fields of the solid propellant micro-rocket before and after treated by PMAO techniques was performed using CFD software.In order to investigate the influence of the coat generated by PMAO techniques on the temperature of the inner wall and exterior wall,the wall temperature in radial direction with and without using the PMAO techniq... |
