Purpose/Aim
Quantitative schlieren diagnostic techniques have been widely used in the diagnosis of plasma properties, which can quantitatively calculate channel plasma parameters with the assumption that the discharge channel is perpendicular to the ground and the channel section is axisymmetric. However, the development trajectory of the leader discharge channel is random. In this paper, the influence of the verticality of the channel and non-axisymmetric is analyzed.
Experimental/Modeling methods
Based on ray optics theory, the model of the LED light source, lens, slit, the channel of discharge, and CMOS chip in the quantitative schlieren diagnostic system is built. A numerical simulation system for quantitative schlieren diagnosis system of stable leader discharge with 3 m air gap is built by COMSOL.
Results/discussion
The simulation results are in good agreement with the experimental results of the quantitative schlieren diagnostic technique for the 3 m air gap, which is shown in Fig. 1. Considering the different random forms of the discharge channel, the change of the radial deflection angle is analyzed.
Conclusions
A simulation model is proposed for a quantitative schlieren diagnosis system which is suitable for long-gap stable leader discharge. When the discharge channel is not perpendicular to the ground, the focal plane deviation will change the slope of the radial deflection angle. When a section of the channel is non-axisymmetric, the maximum of the radial deflection angle will increase obviously if the detect light is through the long axis of the section. And a radial stretching on deflection angle occurs if the detect light is through the short axis of the section.
