Capillarity in Fluid

Capillarity in Fluid

Capillarity describes the movement of liquid in small spaces without external forces acting on it. The capillarity is driven by surface tension and adhesive interactions between the liquid and surrounding solid surfaces. This effect is often seen in narrow tubes, porous materials, and fine particles.
Surface tension is crucial to capillarity. It results from cohesive forces between liquid molecules at the liquid-air boundary, forming a skin that resists external forces. When the capillary tube...

Characteristics of Fluids

Characteristics of Fluids

When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...

Characteristics of Fluids

Characteristics of Fluids

Fluids differ from solids primarily in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, maintaining their shape and resisting deformation. In contrast, fluids have molecules spaced farther apart with weaker forces, allowing them to flow and deform easily.
Fluids, which include both liquids and gases, are substances that deform continuously under shearing stress. For example, water and oil are liquids with molecules that can...

Types of Fluids

Types of Fluids

Fluids can be classified into Newtonian and non-Newtonian fluids based on their response to shear stress. Newtonian fluids have a linear relationship between shear stress and the shear strain rate, following Newton's law of viscosity. Their viscosity remains constant regardless of the shear rate, making their behavior predictable and easier to analyze. Common examples include water, air, oil, and gasoline.
In contrast, non-Newtonian fluids do not follow Newton's law of viscosity, and their...

Surface Tension of Fluid

Surface Tension of Fluid

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.
Surface tension varies with...

Accelerating Fluids

Accelerating Fluids

When a fluid is in constant acceleration, the pressure and buoyant force equations are modified. Suppose a beaker is placed in an elevator accelerating upward with a constant acceleration, a. In the beaker, assume there is a thin cylinder of height h with an infinitesimal cross-sectional area, ΔS.
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

Summary

Fluid elasticity impacts dynamic wetting. Boger fluids, with minimal shear thinning, show elasticity increases curvature near the contact line, driven by the solvent's non-Newtonian behavior, leading to interface instabilities.

Area of Science:

Fluid dynamics
Polymer science
Rheology

Background:

Many industrial polymer solutions exhibit non-Newtonian behavior near moving contact lines.
Previous work showed shear thinning reduces dynamic contact angle dependence on speed.

Purpose of the Study:

Investigate dynamic wetting of Boger fluids, focusing on elasticity-dominated rheology.
Understand the role of polymer elasticity and solvent properties in dynamic wetting.

Main Methods:

Studied Boger fluids, prepared with dilute high molecular weight polymer in an oligomeric solvent.
Analyzed fluid behavior in high shear environments near a moving contact line.

Main Results:

Elasticity in Boger fluids increases curvature near the contact line.
This enhancement is primarily due to the oligomeric solvent's weak non-Newtonian properties.
Observed instabilities on the liquid/vapor interface near the moving contact line.

Conclusions:

Boger fluids demonstrate elasticity's influence on dynamic wetting, though solvent properties play a significant role.
The findings highlight the complex interplay of elasticity and shear thinning in polymer solution wetting phenomena.
Instabilities at the interface warrant further investigation in non-Newtonian fluid dynamics.
