Summary
Gas bubble evolution in liquids is studied, focusing on oxygen in water. Bubble growth, association, and movement to the surface are analyzed to understand fluid dynamics.
Area of Science:
- Physical Chemistry
- Fluid Dynamics
- Chemical Engineering
Background:
- Analyzes the evolution of gas injected into a liquid, using oxygen in water as a model system.
- Examines bubble growth via molecule attachment, bubble association, and movement to the liquid-gas interface.
- Considers gas injection through individual molecule insertion or porous material-mediated bubble formation.
Purpose of the Study:
- To analyze the behavior and evolution of gas bubbles within a liquid medium.
- To investigate the mechanisms of bubble growth, association, and transport.
- To demonstrate a method for visualizing fluid flow using bubble dynamics.
Main Methods:
- Observing the growth of oxygen bubbles in water.
- Analyzing bubble association and upward movement.
- Utilizing bubble size distribution to infer flow patterns.
Main Results:
- Two gas injection methods are evaluated: individual molecules and small bubbles.
- Bubble behavior, including growth and floatation, is analyzed in water.
- Bubbles either disappear or reach the boundary due to turbulent motion.
Conclusions:
- Bubble size distribution measurement aids in mapping flow current lines.
- The theory of bubble growth provides a basis for flow visualization.
- This method allows for the study of fluid dynamics in various regions of a container.

01:13Excess Pressure Inside a Drop and a Bubble
3.8K
The shape of a small drop of liquid can be considered spherical, neglecting the effect of gravity. This drop can further be considered as two equal hemispherical drops put together due to surface tension. The forces acting on the spherical drop are due to the pressure of the liquid inside the drop, the pressure due to air outside the drop, and the force due to the surface tension acting on the two hemispherical drops.

01:18Rise of Liquid in a Capillary Tube
3.5K
When very thin cylindrical tubes, called capillaries, are dipped in a liquid, the liquid rises or falls in the tube compared to the surrounding liquid. This phenomenon is called capillary action. Capillary action occurs due to the combination of two opposing forces: the cohesive forces of the liquid, which cause it to stick to itself and form a rounded shape, and the adhesive forces between the liquid and the walls of the container, which cause the liquid to be attracted to the container walls.

01:22Surface Tension of Fluid
2.0K
Surface tension is a fundamental property of fluids, occurring at the boundary between a liquid and a gas or between two immiscible liquids. This phenomenon arises from the cohesive forces between molecules at the fluid's surface, creating an effect similar to a stretched elastic membrane. Inside each fluid, molecules are equally attracted in all directions by neighboring molecules, but surface molecules experience a net inward force, resulting in surface tension.

6.1K
The expansion of alcohol in a thermometer is one of many commonly encountered examples of thermal expansion, which is the change in size or volume of a given system as its temperature changes. The most visible example is the expansion of hot air. When air is heated, it expands and becomes less dense than the surrounding air, which then exerts an upward force on the hot air to, for example, make steam and smoke rise, and hot air balloons float. The same behavior happens in all liquids and gases,...

Carbonation is a process used to dissolve carbon dioxide gas in a liquid, commonly used in the production of carbonated beverages. Achieving efficient carbonation requires careful control of temperature, pressure, and flow conditions. By adjusting these parameters, carbonation efficiency can be maximized, producing a higher concentration of CO2 in the liquid.
Temperature is a key factor in CO2 solubility. In this case, the CO2 gas and the liquid are cooled to 20°C. Lower temperatures enhance...

In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the...
