Primarily experimental study of an improved travelling wave thermo - acoustic prime engine 热线风速仪低温测速的初步研究
We used anemometers and copper constantan thermocouple respectively to measure velocities and temperatures of all measuring points under various air volumes within the room 用热线风速仪、铜?康铜热电偶分别测量出不同送风量下的室内各个测点的速度和温度。
The paper introduces acquired air rate of flow in admission pipes and fluidity in cylinder on single cylinder or multi cylinder engines with hot - wire anemometer , and demarcation and adjustment method of measure values are provided 摘要本文介绍了利用热线风速仪测量单缸与多缸内燃机进气管内流速、气缸内气体流动以及标定与修正的方法。
Abstract : the hot wire anemometer and the ensemble average method are used to measure and study the dispersion turbulent transient feature in a closed cylindrical explosion bomb . the comparison of the dispersion turbulent parameters from different shapes of closed explosion bombs is presented . the relation between errors and numbers in dispersion turbulent measurement with the ensemble average metod is discussed 文摘:采用热线风速仪和系综平均法测定和研究了封闭圆柱形粉尘爆炸罐内扬尘湍流的瞬态特性,并与球形爆炸容器内已测定的扬尘湍流瞬态特性进行了比较,对系综平均法用于扬尘湍流的测量误差与测量次数的关系进行了探讨。
