Method for controlling bubbles to adhere to super-aerophilic orbit on vertical or slant upper surface

Abstract

The invention discloses a method for controlling bubbles to adhere to a super-aerophilic orbit on a vertical or slant upper surface. With the method, on the condition without energy input, bubbles canadhere to the super-aerophilic orbit as needed. Specifically, a super-hydrophilic flow guide plate which inclines in the direction of gravity according to a certain angle of alpha is arranged on thearea, close to a wall, of the super-aerophilic orbit; and when bubbles make contact with the super-hydrophilic flow guide plate under the action of buoyancy of themselves or upward drag force, and because of the super-aerophilic performance of the super-hydrophilic flow guide plate, bubbles move in the guiding direction of the super-hydrophilic flow guide plate till bubbles adhere to the super-aerophilic orbit smoothly and move along the super-aerophilic orbit. According to the method for controlling bubbles to adhere to the super-aerophilic orbit on a vertical or slant upper surface, bubblesare controlled to go up to float, the speed of bubbles going up is under control, no energy is input, and bubbles go up just by virtue of the buoyancy of themselves, and under the action of the factors such as the stressed drag force and wall surface adhesion force while the track of bubbles going up is under control. The method for controlling bubbles to adhere to the super-aerophilic orbit on the vertical or slant upper surface is high in applicability, the super-hydrophilic flow guide plate can be adjusted in curve radian to adapt to bubbles of different sizes, so that the purpose of controlling different bubbles to go up to float is achieved.

Description

technical field [0001] The invention relates to the control of bubble movement in water or aqueous solution, and belongs to the technical field of multiphase flow and energy saving. Background technique [0002] The movement of bubbles in liquid is a typical problem in gas-liquid two-phase flow, and gas-liquid two-phase flow is a research hotspot in current multiphase flow research and engineering applications. When the bubbles move in the liquid, they will be affected by buoyancy, gravity and other forces. These forces make the bubbles move in the liquid and disturb the flow field, and the flow field reacts on the bubbles. The bubbles are disturbed by the flow field, making them flow in the liquid The motion in the liquid is very complicated, which makes it difficult to control the upward trajectory of the bubble in the liquid. [0003] Discrete bubble two-phase flow widely exists in petrochemical, energy, shipbuilding, sewage treatment and other engineering equipment and ...
