Description

technical field [0001] The invention belongs to the technical field of material processing, and in particular relates to a particle suspension dynamic focusing heating system based on composite ultrasonic technology and a heating method thereof. Background technique [0002] With the continuous deepening of the research on condensed matter, people's requirements for experimental conditions are becoming more and more stringent. The space environment is such a special environment. It is an ideal experimental condition for the study of phenomena. Aerospace technology has developed rapidly in the past few decades, but the space resources that people have obtained so far are still very limited, so ground methods for simulating various effects in the space environment have emerged as the times require. Acoustic levitation technology can be used to simulate the containerless state in the space environment, and the containerless melting of materials on the ground can prevent the cr...

Problems solved by technology

[0003] For the heating method of suspended materials, the existing heating methods mainly focus on methods such as laser heating and electromagnetic heating, but these methods have obvious shortcomings

The laser heating method can only be used for transparent materials. For non-transparent materials, the laser is difficult to penetrate, and the energy cannot be transmitted to a specific area; the electromagnetic heating method has special requirements for the material, that is, the material must be conductive and magnetic. limits
