Problems solved by technology
In flowing water, the multi-scale and complex flow environment makes it extremely difficult to observe the growth process, stable residence and residence of microbubbles in micro-nano pits. At present, there is no dynamic microscopic observation device for microbubbles. , can make the microbubbles stay stably in the low-speed water flow and observe the growth process and residence situation of the microbubbles in the micro-nano pits in real time at the micro scale. Provide a certain basis for experiments in order to achieve a significant reduction in the underwater resistance of underwater vehicles

An electrolytic microbubble stability observation test device relates to the technical field of active drag reduction for underwater vehicles, including a microbubble stability observation platform, an electronic flow meter, and a stepless speed-regulating water pump. The interior of the microbubble stability observation platform is Along the direction of fluid movement, trapezoidal diffuser, energy dissipation orifice, honeycomb rectifier, screen, micro-nano pit electrolytic observation test piece, spring probe, carbon rod are arranged in sequence, and the front end of the micro-bubble stability observation platform passes through the water The pipeline is connected with the electronic flowmeter and the stepless speed regulating water pump, the spring probe is connected to the negative pole of the power supply through the power wire, and the carbon rod is connected to the positive pole of the power supply. Through the multiple effects of trapezoidal expansion section, energy dissipation orifice, honeycomb rectification net and screen, energy dissipation, vertical rectification, and horizontal rectification, the dynamic water flow can reach a stable state, which is beneficial to the microbubbles. Stable residence and observation of microbubble growth history and residence status in micro-nano pits at the micro scale.
Description
technical field [0001] The invention relates to the technical field of active drag reduction for underwater vehicles, in particular to an electrolytic microbubble stability observation test device. Background technique [0002] In recent years, the improvement of the propulsion speed, maneuverability, and strike accuracy of underwater anti-submarine and anti-ship combat navigation weapons has become the key to my country's dominance of the sea. Guidance ability, because its attack range is below the waterline, once it hits the target, it can effectively destroy the combat effectiveness of the enemy ship. In order to be able to effectively strike the target, the speed of the underwater combat weapon must reach 1.5 times the target speed, and the faster the speed, the stronger the destructive power, otherwise it will not cause enough damage to the enemy ship, or even fail to hit the target. The resistance of an underwater navigation vehicle is about 1,000 times that of an aeri...
