Features of Jets Formed by Erosive Capillary Discharges

چکیده
An experimental study of the physical processes in a thin plasma jet produced by the pulsed discharges in the capillary with evaporated wall is described. The losses in mass from capillary wall as well as the transferred charge are accurately measured. The velocity of plasma jet propagation is measured, too. The current structure in plasma is studied. It is proved that a thin plasma jet can be obtained through capillary manufactured from not only polymer but also inorganic materials.

One of the most concerning issues for researchers is to predict the shape and dimensions of the scour pit nearhydraulic structures such as the base of bridges, weirs, valves and stilling basins due to both financial and humanhazards induced by destruction of the structure. As the scour issue has its own complexity in relation to themultiplicity of effecting factors on it, in this study therefor...
متن کاملHigh-pressure micro-discharges in etching and deposition applications
High-pressure micro-discharges are promising sources of light, ions, and radicals and offer some advantages in materials processing applications as compared to other more conventional discharges. We review here results from etching experiments using stencil masks where the discharge is formed only in the pattern cutout. The mask consists of a thin metal-dielectric structure and is pressed again...
