A symmetrically arranged electrodes for corona discharge anemometry

This paper presents a novel anemometry based on bipolar corona discharge probe with symmetrically arranged parallel electrodes, which is potentially applicable for in-situ measurement. With the proposed configuration, under the existence of the airflow, the decomposed gas is redistributed towards the downstream electrode, and changes the current-voltage characteristics of the system. Experimental study on the anemometry characteristics demonstrates the possibility of measuring a wide range of air flow rate/ flow velocity, i.e., up to 80 l/m.
