Investigation on the Length and Temperature of an Ar Plasma Jet Driven by Sinusoidal High Voltage
摘要
Abstract
Length and temperature are two important parameters of the atmospheric plasma jet. An argon plasma jet has been generated in the atmospheric environment driven by 10 kHz sinusoidal high voltage. The length and tem-perature of the plasma jet were measured by the optical and electrical instruments. The results show that the length of the plasma jet increases with the applied voltage,but first increases with the flow rate and then decreases gradual-ly with a further increase of the flow rate. The jet temperature and the electron excited temperature were measured and calculated by the optical fiber thermometer and spectrometer. The jet temperature is closed to the room tempera-ture and the electron excited temperature is less than 1.5×104 K,which is among the range of the cold plasma. Mo-reover,both of them rise with the voltage increasing.关键词
