摘要
针对三维非等温湍流流场,本文开发了一种双热线多方位转动测量的新方法,它可同步测量三维湍流参数、动态温度场以及它们的脉动相关量。这不仅在热线测量技术新方法的开发上、具有极广泛的应用前景,而且为湍流基础实验和研究工作(如探讨湍流脉动关联关系的基础研究)的开展,提供了新的手段。
This paper develops a method dealing with a heated turbulent three-dimensional flow by employing a rotating two-wire-probe, the velocity, temperature and their fluctuation correlation terms are measured simultaneously. Not only has this method very valued useful prospects on developing the new hot-wire measureing method, but also provides new means for expanding both basic experiments and researches, for example, discussing the auto-and cross correlation about fluctuating turbulent parameters.
