Abstract EN
A new plasma anemometer based on AC glow discharge is designed in this article.
Firstly, theoretical analysis of plasma anemometer working principle is introduced to prove the feasibility of the experimental measurement method.
Then the experiments are carried out to study the effects of different parameters on the static discharge characteristics of the plasma anemometer system, by which the system optimization methods are obtained.
Finally, several groups of appropriate parameters are selected to build the plasma anemometer system based on resistance capacitance coupling negative feedback AC glow discharge, and different airflow speeds are applied to obtain the achievable velocity measurement range.
The results show that there is a linear relationship between airflow velocity and discharge current in an allowable error range, which can be applied for airflow velocity measurement.
Negative feedback coupling module, which is composed of the coupling resistance and the coupling capacitance, has good effects on improving the system stability.
The measurement range of the airflow velocity is significantly increased when the electrode gap is 3 mm, coupling resistance is 470 Ω, and coupling capacitance is 220 pF.
