Surface Tension of Fluid01:22

Surface Tension of Fluid

535
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...

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

487
Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the...

Excess Pressure Inside a Drop and a Bubble

2.3K
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.

Precipitate Formation and Particle Size Control

1.0K
In precipitation gravimetry, the precipitating agent should react specifically or selectively with the analyte. While a specific reagent reacts with the analyte alone, a selective reagent can react with a limited number of chemical species.
The obtained precipitate should be either a pure substance of known composition or easily converted to one by a simple process, such as ignition or drying. In addition, the precipitate should be insoluble and easily filterable. In general, filterability...

Precipitation Processes

The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...

Area of Science:

  • Fluid dynamics
  • Surface science
  • Physics

Background:

  • Droplet impingement on solid surfaces is influenced by liquid properties, velocity, and surface conditions (wettability, roughness).
  • Predicting droplet splashing remains a challenge in fluid dynamics.

Purpose of the Study:

  • To develop a predictive model for droplet splashing based on physical principles.
  • To investigate the influence of surface characteristics on splashing behavior.

Main Methods:

  • Utilizing a pressure balance model for the liquid film beneath the droplet.
  • Employing a modified energy balance equation to analyze droplet dynamics.
  • Investigating the role of hydrodynamic, hydrostatic, capillary, and viscous pressures.

Main Results:

  • Splashing occurs when driving forces (hydrodynamic and hydrostatic pressures) overcome opposing forces (capillary pressure and viscous stress).
  • The model successfully predicts splashing based on pressure and energy balances.
  • Wettability and surface roughness significantly affect splashing conditions.

Conclusions:

  • A novel approach combining pressure and energy balance effectively predicts droplet splashing.
  • Understanding these physics is vital for optimizing droplet-based technologies.
  • Findings have implications for printing, cooling sprays, and pesticide application.
