Electrolytic microbubble stability observation test device

Abstract

The invention relates to an electrolytic microbubble stability observation test device, relates to the technical field of active drag reduction of underwater vehicles and comprises a microbubble stability observation platform, an electronic flowmeter and a stepless speed regulation water pump. A trapezoidal diffusion section, an energy dissipation pore plate, a honeycomb rectification net, a screen, a micro-nano pit electrolysis observation test piece, a spring probe and a carbon rod are sequentially arranged in the microbubble stability observation platform in the fluid movement direction, and the front end of the microbubble stability observation platform is connected with the electronic flowmeter and the stepless speed regulation water pump through water pipelines; and the spring probeis connected with the negative electrode of the power supply through a power lead and the carbon rod is connected with the positive electrode of the power supply. Through the combined action of multiple effects of flow stabilization, energy dissipation, vertical rectification and horizontal rectification of the trapezoidal diffusion section, the energy dissipation pore plate, the honeycomb rectification net and the screen, the dynamic water flow reaches a stable state, stable residence of microbubbles is facilitated, and the growth process and the residence clear condition of the microbubblesin the micro-nano pit can be observed under 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...

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
