Abstract:A new approach to establish the circuit model of alternating current (AC) plasma anemometer is proposed. Firstly, experimental system is introduced to illustrate the experimental studies. Then all circuit models are built on basis of theoretical and experimental analysis, including the equivalent circuits of the positive column space and the sheath, the circuit models of AC plasma anemometer without airflow and under airflow, parameter matching of the equivalent circuit models without airflow and under airflow. Finally, the circuit models are verified by comparing the simulation currents with experimental currents. The final circuit model takes into account the whole framework of AC plasma anemometer containing the positive column space, the sheath and the diffusion region, which is proved feasible and reliable, and it can provide an effective tool for the future research of AC plasma anemometer.
