Embodiment Construction
[0024] The present invention will be further described below in conjunction with accompanying drawing:
[0025] (1) Charging device
[0026] Mainly use two regulated power supplies, one low-voltage regulated power supply (input AC 220V output DC 12V), the other high-voltage regulated power supply (input direct voltage 12V output direct voltage 2000V), and add an anti-backflow device to stabilize the high-voltage capacitor Charge). In order to realize the adjustable output of the power supply voltage, a 10K potentiometer is connected in series at both ends of the power supply, and the output voltage of the power supply can be controlled by adjusting the resistance of the potentiometer.
[0027] (2) Discharge device
[0028] Connect several sets of 20uf capacitors with a rated voltage of 2000V in parallel, and connect them to the power supply and the two ends of the two electrodes respectively. The light source is on the same level, and the water tank is filled with degassed ...

Abstract
The invention particularly relates to an adjustable high-voltage and large-scale bubble generating device under the laboratory condition. The adjustable high-voltage and large-scale bubble generating device comprises a charging device, a discharging device, a measuring device and a safety device. With the adoption of the adjustable high-voltage and large-scale bubble generating device, the problem that the buoyancy is not obvious due to small bubble size in the prior art is solved, and large-scale bubbles can be generated by high voltage successfully; and the device further can be connected with a plurality of electrodes externally, so that different numbers of bubbles are generated synchronously and asynchronously, meanwhile, more accurate values are provided for simulating an underwater explosion bubble experiment, and compared with a low-voltage discharging device, the adjustable high-voltage and large-scale bubble generating device has an irreplaceable function in the field of large-scale bubble pulse research.
Description
technical field [0001] The invention specifically relates to an adjustable high-voltage large-scale bubble generation device under laboratory conditions. Background technique [0002] The dynamic characteristics of air bubbles in water have always been an important and fundamental issue concerned by many fields. Air bubbles are widely used, including petroleum exploration, chemical industry, marine environment, medical treatment and other fields. Due to the complexity of bubble movement, the research on various characteristics of bubbles is still insufficient, and many unknown mechanisms remain to be explored. The research methods are divided into two methods: experimental design and numerical simulation. Among them, experimental design is the most direct means for people to understand bubbles, and it provides an effective means of verification for numerical simulation. However, at present, the scale of bubbles generated by means of non-drug explosion under laboratory condi...
