摘要
本文综合分析了目前采用热线风速仪测量紊流流场的各种方法,并着重指出,在高紊流度情况下,还没有比较可靠的方法。在使用目前推荐的各种计算公式时,必须首先验证其公式的可靠性,并注意其限制性条件。
This paper synthetically analyses various methods measu- ring turbulent flow field with the hot wire anemometer,and points out that untill now there still have not any very reliable measuring methods in high level turbulent.When using any formula recommended by some papers,first of all we must check its correctness,then pay attention to its limited condition.
