Structure Improvement and Test Analysis of Water Calorimeter Based on Micro-channel Cooling
高声速飞行器再入过程中面临严峻的气动加热环境,最高气流温度可达上万摄氏度,常用量热计在如此高的气流温度下,缺乏良好的热流测试性能和热负荷生存能力.为解决地面试验中高超声速飞行器模型表面高热流的连续、精准测量难题,研发了一种基于微流道冷却的新型水卡式量热计,其内部微型流道结构采用 3D打印技术构建.通过数值仿真,确定了新型水卡式量热计的微流道尺寸与布局,与同一冷壁热流的传统水卡式量热计相比,其核心区域温升降低近50%,验证了微流道水卡式量热计在极端…查看全部>>
The aerodynamic heating environment encountered during hypersonic flight or reentry from space is severe in which the highest temperature can even reach 10000℃,resulting in a failure of commonly used calorimeterts showing great heat flux testing performance and thermal load viability.An new water calorimeter based on micro-channel cooling was developed in order to solve the problem of continuous and accurate measurement of high heat flux on the surface of hi…查看全部>>
