A drop or droplet is a small column of liquid, bounded completely or almost completely by free surfaces. A drop may form when liquid accumulates at the end of a tube or other surface boundary, producing a hanging drop called a pendant drop.

2001年5月1日 · Whether standing in the shower, spilling the morning coffee or going to work in the rain, each day typically begins with water droplets splashing off a solid surface. In fact these phenomena are so common that they often go unnoticed.

2014年4月13日 · Viscosity helps create a shape that lets liquid pop off the surface it strikes. The flow of fluids is one of the most complex, beautiful, and amazing things in physics. Slow motion pictures of...

2018年6月5日 · A water drop is composed of water molecules that like to stick together-an example of the property of cohesion. In the picture of pine needles above, the water droplets are stuck to the end of the pine needles-an example of the property of adhesion.

2019年6月28日 · Water droplets form as little spheres thanks to surface tension. This force binds water molecules at a droplet’s surface and tugs the molecules inward, forming the shape.

2018年2月9日 · Understanding the behaviour of water droplets can help biophysics students get a better appreciation for the potential applications and challenges of lab-on-a-chip, while applied physics and engineering students may encounter droplets as condensation on cold surfaces.

2021年3月31日 · In this post, we will investigate the forces acting on the droplets in natural phenomena and practical applications, and use order-of-magnitude analysis to determine the dominant force. Knowing the dominant force, we can predict the fate of the droplet.

2021年3月1日 · After comprehensive understanding of the water droplet bouncing phenomena and mechanisms, numerous advanced droplet bouncing-based applications were developed, such as surface self-cleaning, anti-smudge, anti-fouling, deicing, directional droplet transportation and heat transfer enhancement.

2017年10月18日 · Two researchers, using laser-flash photography of microscopic droplet-particle collisions, have discovered that water droplets still have liquid tricks to reveal.

2024年10月5日 · In real-time, and on a molecular scale, materials scientist Vinayak Dravid of Northwestern University and his colleagues watched as the tiniest bubble of water ever seen bloomed seemingly out of thin air.
