This application relates to a flow field velocity measurement device based on electric arc plasma. The device includes a high-voltage power supply module, a load module, a negative feedback RC coupling module, a gas flow supply module, an optical observation module, a data acquisition and processing module, and a water cooling module. The high-voltage power supply module provides a controllable high-frequency AC voltage to the load module. The load module employs non-directly facing conical electrodes; when the gas between the electrodes is broken down, electric arc plasma is generated. The negative feedback RC coupling module is used to suppress the positive feedback process of gas discharge, achieving stable gas discharge. The optical observation module assists in electrode spacing calibration and plasma morphology observation. The gas flow supply module provides a continuously adjustable gas flow. The data acquisition and processing module collects and processes the voltage and current of the electric arc plasma at different wind speeds to obtain the flow field velocity. This device can achieve high-resolution time-correlated sequential flow field velocity measurement of hypersonic flow.
