|November 2, 1984
Resumen
Nunca se observó que las gotas individuales que impactan en las superficies líquidas rebotaran. La tensión superficial domina la absorción y el rebote de la corriente de gotas, con la conservación de la energía y el impulso explicando las interacciones.
Área de la Ciencia:
- Dinámica de fluidos La dinámica de fluidos.
- Física de la superficie de las superficies.
Sus antecedentes:
- Los fenómenos de impacto de gotas son cruciales en varios procesos industriales y naturales.
- Comprender el comportamiento de las gotas, incluida la absorción y el rebote, es esencial para predecir las interacciones de los fluidos.
Objetivo del estudio:
- Investigar experimentalmente la absorción y el rebote de gotas individuales y corrientes de gotas que impactan en una superficie líquida profunda.
- Establecer criterios para el impacto y la absorción de la corriente de gotas.
- Para identificar los mecanismos físicos dominantes que rigen estas interacciones.
Principales métodos:
- Examen experimental de la gota (diámetro < 1200 micrómetros) impactos en un líquido profundo.
- Aplicación de la conservación de la energía mecánica y los principios del momento.
- Análisis de los efectos de la tensión superficial en el comportamiento de las gotas.
Principales resultados:
- Las gotas individuales fueron constantemente absorbidas y nunca se observó un rebote.
- La tensión superficial fue identificada como el principal factor que influye en el comportamiento de las gotas.
- Se desarrollaron criterios de impacto para las corrientes de gotas, diferenciando la absorción del rebote.
Conclusiones:
- El comportamiento de las gotas de impacto se rige predominantemente por la tensión superficial.
- Los impactos de una sola gota resultan en la absorción, no en el rebote.
- Los criterios establecidos proporcionan un marco para la comprensión de las interacciones de gota-flujo-líquido.

01:22Surface 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
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...

01:24Surface Tension
Surface tension is defined as the force per unit length (γ) acting along the surface of a liquid. It arises due to strong intermolecular forces of attraction. A molecule located inside the bulk of the liquid is surrounded by other molecules and experiences equal forces in all directions. However, a molecule at the surface experiences unbalanced forces because there are more neighboring molecules below than above. This creates a net inward force that pulls surface molecules toward the interior,...
01:13Contact Angle
When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive force...

01:16Surface Tension and Surface Energy
When a paint brush is immersed in water, the bristles wave freely inside the water. When it is taken out, the bristles stick together. The reason behind this effect is surface tension.
Consider a beaker filled with liquid. The bulk molecules in the liquid experience equal attractive forces on all sides with the surrounding molecules. However, the surface molecules experience a net attractive force downward due to the bulk molecules. The surface of the liquid behaves like a stretched membrane,...

01:07Cohesion
Cohesion is the attraction between molecules of the same type, such as water molecules. Water molecules have an overall neutral charge but are polar molecule. An oxygen atom in one water molecule has a partial negative charge that can bind to a hydrogen atom with a partial positive charge in a second water molecule, forming a hydrogen bond. Each water molecule can form up to four hydrogen bonds with other water molecules. Hydrogen bonds are responsible for water's cohesive nature.
