Description
Technical field
The present invention relates to laminar flow plasma technology fields, more specifically to a kind of laminar flow plasma generator cathode knot
Structure.
Background technique
Plasma state is the 4th state of substance, and almost the substance (not including still unacknowledged dark matter) of 99 ﹪ is all in universe
In plasma state.Plasma jet and general fluid have similitude in flow characteristics, and there are two types of flow regimes for tool: laminar flow
With turbulent flow.To a certain given fluid, when its flow velocity is less than a particular value, fluid makees well-regulated stratiform or the movement of a fluid stream shape,
Fluid particle does not have transverse movement, advances without interfering with each other between particle, and this liquid form is laminar flow；It is somebody's turn to do when fluid flow rate is greater than
When value, the well-regulated movement of fluid is destroyed, and there are also additional transverse movement, fluids other than main longitudinal movement for particle
Particle staggeredly confusedly advances, and this liquid form is turbulent flow.
