| 摘 要： | 建立了基于瞬态实验技术的风洞和测试系统,用HSV色彩模型对颜色进行描述,得到颜色-温度关系;用半无限大导热理论对瞬态导热过程进行换热系数求解.测量了平板表面的换热系数分布,并与理论解进行了对比,两者相吻合.

| Abstract: | A wind tunnel aud data acquisition system for transient experiment are setup. HSV color space is used to interpret the color and to determine the color versus temperature relation. The heat transfer coefficient is obtained by solution of selni-iufinity heat conduction theory. The heat transfer coefficient distribution of a flat plate surface is surveyed by the method and the resuhs are agreed with the theory solution. |
