Summary
Particle adhesion to surfaces is driven by capillary forces. This study reveals dynamic liquid bridge formation and ripple effects, showing adhesion forces change over time.
Area of Science:
- Physics
- Fluid Dynamics
- Surface Science
Background:
- Capillary adhesion, driven by liquid bridge formation, causes particles to stick to surfaces.
- While static capillary adhesion is understood, the dynamic process of liquid bridge formation is complex.
Purpose of the Study:
- To experimentally investigate the dynamic evolution of a liquid bridge after particle-surface contact.
- To understand how surface ripples influence meniscus growth and capillary force dynamics.
Main Methods:
- Experimental study of a glass sphere gently contacting a thin viscous liquid film.
- Observation and analysis of liquid bridge and surface ripple evolution.
Main Results:
- Initial contact generates a ripple on the liquid film, coupled with meniscus growth.
- A distinct second regime emerges when the ripple detaches from the liquid bridge.
- Capillary forces are shown to be time-dependent due to these dynamic effects.
Conclusions:
- The dynamic evolution of liquid bridges significantly impacts particle adhesion.
- Surface ripples play a crucial role in the initial stages of meniscus formation.
- Understanding these dynamics is essential for predicting and controlling adhesion in real-world scenarios.

6.0K
When water is poured into a glass, it falls freely and quickly, whereas if honey or maple syrup is poured over a pancake, it flows slowly and sticks to the surface of the container. This difference in the flow of different kinds of liquids arises due to the fluid friction between the liquid layers and the liquid and the surrounding material. This property of fluids is called fluid viscosity. In this example, water has a lower viscosity than honey and maple syrup.

01:19Viscosity of Fluid
529
Viscosity measures the resistance a fluid offers to flow and deformation. It results from internal friction between layers of fluid moving relative to one another. Dynamic viscosity, denoted by the Greek letter mu (μ), quantifies the force needed to move one fluid layer over another. For Newtonian fluids like water and air, the relationship between the shearing stress and the rate of shearing strain is linear, meaning their viscosity remains constant regardless of the applied stress.

Surface Tension
The various IMFs between identical molecules of a substance are examples of cohesive forces. The molecules within a liquid are surrounded by other molecules and are attracted equally in all directions by the cohesive forces within the liquid. However, the molecules on the surface of a liquid are attracted only by about one-half as many molecules. Because of the unbalanced molecular attractions on the surface molecules, liquids contract to form a shape that minimizes the number...

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.

01:23Design Example: Deciding Thickness of Lubricating Fluid in a Shaft

Effective lubrication between a rotating shaft and its bearing housing is essential in rotating machinery to minimize friction, wear, and energy loss. With carefully controlled thickness and viscosity, the lubricant layer prevents metal-to-metal contact, ensuring smooth operation.
To calculate the required thickness of the lubricant layer, the tangential velocity at the shaft's surface must first be determined. This velocity is calculated by converting the rotational speed to angular...

01:18Rise of Liquid in a Capillary Tube
1.9K
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.
