Abstract
The dynamic emitter-a nozzle with a disposed along its axis central conic body-is a new engineering decision. The phenomena arising during its work are valuable and prospective both in fundamental science and practical application. During our experiments with this device we have discovered spiral-twisted non-ideal plasma wave structures arising in subsonic and supersonic gas jets flowing from the nozzle with a central cone. We consider very important and prospective the fact that the flow from the dynamic emitter remains almost stable both in shape and power with the distance from the nozzle outlet increasing. For example, the air jet from the nozzle with a central cone can deflect a steel plate of weight 2.55 kg, pending on the 120 mm wire, for about 45 mm at the distance of 400 mm. At this distance the power of the flow from the common conic nozzle is insignificantly low. Also in our experiments we registered phase transitions of air, argon and nitrogen to liquid and solid in the jets at room conditions (temperature of the jet was 285 K, humidity about 5-7%), which is very unusual and provides a lot of practical opportunities. Water vapor flowing from the dynamic emitter creates the mentioned non-ideal plasma structures with increased density of electrons that provides concentration of energy in small volumes (in the nodes of the structure) and high energy radiation (in the experiments there were detected electromagnetic fields up to 1 GHz). The received results can be explained with introducing the concept of electromagnetic super-compressibility which has been the primary aim of our work.
