摘要

在高速热喷流条件下

对二元收扩喷管超音段壁面的冷却进行了初步试验研究。采用的冷却方案共有3种

分别是缝隙式、离散孔式和波纹板式气膜冷却方案。得到了各冷却方案喷管的壁面压力分布、壁温分布和红外辐射特性。结果表明:冷却气流对喷管壁面压力分布影响较大

不同冷却结构的壁面压力分布特点不同。通过冷却

各喷管的壁温和红外辐射强度明显降低。

Abstract

At high speed and hot exhaust flow conditions

a preliminary experimental investigation on the divergent wall cooling of Two Dimensional C D Nozzle had been conducted.There were three film cooling schemes used

namely

slot

discrete hole and wiggle strip.In the experiment

the infrared radiation and axial distribution of wall temperature and near wall flow pressure were measured with and without film cooling.The results showed:The cooling had significant influence on the near wall flow pressure

and the influence was different with cooling schemes.The infrared radiation and wall temperature were obviously decreased by cooling.There were better benefits through cooling by slot and wiggle strip film cooling.
