Description

Technical Field

[0001] The utility model relates to a bubble display system, in particular to a multi-scale bubble display system. Background Art

[0002] Bubble flow is a common gas-liquid two-phase flow in various energy industries. The characteristic of bubbly flow is that the gas phase is discontinuous, and the gas phase in the form of small bubbles is distributed in the continuous liquid. Most of the bubbles are spherical. Bubbles of different diameters affect the mass transfer efficiency between the gas phase and the liquid phase. The bubble diameters required for bubbly flow are different under different experimental conditions. The presence of millimeter-level and micron-level bubbles can increase the mass transfer efficiency of the gas-liquid two-phase. When the bubble size reaches the nanometer level, the presence of nanobubbles can change the wall turbulence structure and achieve the effect of reducing flow resistance.

[0003] The bubbles in the bubbly flow are multi-scale, that is, of different sizes. Currently, there is no multi-scale bubble display system for observing the floating speed of bubbles of different sizes and the state of bubbles in water. Summary of the invention

[0034] Working principle of the multi-scale bubble display system:

[0035] According to Stoke's law, the rising speed of bubbles in water is proportional to the square of the bubble diameter. The smaller the bubble diameter, the slower the rising speed of the bubble. From the relationship between the rising speed of bubbles and the bubble diameter, it can be seen that the rising speed of bubbles with a diameter of 1mm in water is 6m / min, while the rising speed of bubbles with a diameter of 10μm in water is 3mm / min, which is 1 / 2000 of the former. If the increase in specific surface area is taken into account, the solubility of micro-nano bubbles is 200,000 times greater than that of ordinary air.

[0036] The utility model is used for observing the floating speed of bubbles of different sizes and the state of the bubbles in water, and the observation is more detailed and more intuitive.
