Device for Gravitational Collapse of Bubbles Using Ultrasonic Cavitation

Abstract

A device (100) and method for achieving deuterium-deuterium thermonuclear fusion by means of ultrasonic cavitation. The device (100) comprises: a liquid storage container (1), a sample (2), an ultrasonic transducer (3) and a double-layer electric field. The sample (2) is provided in a deuterium-containing fluid medium (a). The ultrasonic transducer (3) comprises a transducer body (31) and a horn (32). The horn (32) extends into the deuterium-containing fluid medium (a) and is separate from the sample (2). The horn (32), driven by the transducer body (31), vibrates ultrasonically to cause the deuterium-containing fluid medium (a) to undergo ultrasonic cavitation to form cavity bubbles, and to drive the cavity bubbles to move towards the sample (2). The double-layer electric field, provided between the ultrasonic transducer (3) and the sample (2), accelerates the cavity bubbles so as to cause gravity collapse of the cavity bubbles, achieving deuterium-deuterium thermonuclear fusion.

Description

technical field [0001] The invention relates to the technical fields of tribology and nuclear physics, and more particularly relates to a device for realizing gravitational collapse of cavitation bubbles by using ultrasonic cavitation. Background technique [0002] Due to the depletion of fossil energy and the increasingly prominent environmental problems caused by the massive consumption of energy, in recent decades, nuclear fusion research, which is the end solution to human energy problems, has always been the top priority of scientific research in developed countries. Deuterium, a relatively cheap nuclear fusion material, can be obtained by refining seawater, which contains enough deuterium for human use for hundreds of billions of years. The difficulty in realizing controllable thermonuclear fusion lies in how to generate and maintain an extremely high temperature / high pressure environment. To solve this problem, scientists have been struggling for more than half a cent...

Problems solved by technology

However, this experiment has not been able to be repeated, nor has it been recognized by the academic community

Suslick published a paper in PRL in 2007, claiming that 9 neutron counts at 2.45MeV were obtained after 2300 scans, but the data is difficult to distinguish from the 5 neutron counts at the background

So far, fusion research based on the control of bubble wall dynamics through ultrasonic drive has not been truly successful.
