- Abstract:
- This article introduces the detection method of the small throat diameter sonic nozzle by using a bell-type gas flow standard facility and its advantages. The related experiment researches have been done. It also describes the structure styles and the working principles. Meanwhile, it assesses the uncertainty of the outflow coefficient C for the small throat diameter sonic nozzle detected in this method. The feasibility of the detection method has been verified through the experiment data analysis.
