Abstract

The invention discloses a laminar plasma jet stabilizing method and relates to the technical field of plasma jets. The method includes when a plasma source operates, allowing the operation gas to enter an anode member to flow into a gas channel of the plasma source and enters an arc channel finally. The method is simple, the heat released in the anode member cooling process can be utilized reasonably to heat the operation gas, the pressure of the operation gases inside and outside the arc channel can be reduced, the plasma jet can be stabilized, the self cooling of the plasma source can be implemented, the anode member energy utilization rate can be increased, energy waste can be avoided, and the heating efficiency of a high laminar plasma generator can be improved.

Description

technical field [0001] The invention relates to the technical field of plasma jets, more precisely to a method for stabilizing laminar plasma jets. Background technique [0002] Inside the plasma generator, the gas temperature in the gas flow channel is very different from the gas temperature in the arc channel, and the gas pressure in the two channels is different in a certain space volume, and the gas in the arc channel produces a reverse thrust on the gas in the gas flow channel. The working gas flow rate of the laminar plasma jet is generally very small, only about 1-30slpm. This reverse thrust will cause a short-term blockage of the airflow in the airflow channel, and then the reverse thrust will be reduced until it disappears, and the blockage will be eliminated. When the laminar plasma generator is working, this reverse thrust will be generated and disappeared periodically, which causes the laminar plasma jet to be unstable. [0003] In addition, the gas flow channel...
