摘要
某燃烧室火焰筒壁面采用冲击+逆向对流+气膜冷却技术,火焰筒头部采用冲击+对流冷却技术。本文通过计算并与试验结果对比分析表明:该火焰筒的冷却设计基本合理、可行,经进一步的改进和完善后,可作为高温升燃烧室火焰筒的优选设计方案之一。
One combustor flame tube wall was designed to use impingement-counterflow convection-film cooling technique, it＇s flame tube head shield to use impingement-convection cooling. In this paper, the calculated results were compared with experimental dada. Analyses indicated the compound cooling design of combustor flame tube is feasible. With further improvement, this design can be used as one of cooling schemes of high temperature rise combustor flame tube.
