本文从理论上分析了在吹吸气流中临界断面的位置,推导了计算临界断面位置的方法,并得到试验验证;同时指出污染气流是影响临界断面最有利位置的因素之一。
This paper theoretically analyzes the position of the critical section in the blowing and inhalation air flow, deduces the method for calculating the critical section location, and obtains experimental verification. At the same time, it points out that the pollution air flow is one of the factors affecting the most favorable position of the critical section.
