  2. Droplet-based microfluidics - Wikipedia

    en.wikipedia.org/wiki/Droplet-based_Microfluidics

    Droplet-based microfluidics often operate under low Reynolds numbers to ensure laminar flow within the system. [2] Droplet size is often quantified with coefficient of variation (CV) as a description of the standard deviation from the mean droplet size. Each of the listed methods provide a way to generate microfluidic droplets in a controllable ...

  3. Vapor–liquid–solid method - Wikipedia

    en.wikipedia.org/wiki/Vapor–liquid–solid_method

    The materials system used, as well as the cleanliness of the vacuum system and therefore the amount of contamination and/or the presence of oxide layers at the droplet and wafer surface during the experiment, both greatly influence the absolute magnitude of the forces present at the droplet/surface interface and, in turn, determine the shape of ...

  4. Plateau–Rayleigh instability - Wikipedia

    en.wikipedia.org/wiki/Plateau–Rayleigh_instability

    Three examples of droplet detachment for different fluids: (left) water, (center) glycerol, (right) a solution of PEG in water. In fluid dynamics, the Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same total volume but less surface area per droplet.

  5. Sessile drop technique - Wikipedia

    en.wikipedia.org/wiki/Sessile_drop_technique

    In materials science, the sessile drop technique is a method used for the characterization of solid surface energies, and in some cases, aspects of liquid surface energies. [1] The main premise of the method is that by placing a droplet of liquid with a known surface energy and contact angle , the surface energy of the solid substrate can be ...

  6. Kelvin equation - Wikipedia

    en.wikipedia.org/wiki/Kelvin_equation

    When the Laplace pressure rises in a droplet, the droplet tends to evaporate more easily. When applying the Kelvin equation, two cases must be distinguished: A drop of liquid in its own vapor will result in a convex liquid surface, and a bubble of vapor in a liquid will result in a concave liquid surface.

  7. Drop (liquid) - Wikipedia

    en.wikipedia.org/wiki/Drop_(liquid)

    The term droplet is a diminutive form of 'drop' – and as a guide is typically used for liquid particles of less than 500 μm diameter. In spray application , droplets are usually described by their perceived size (i.e., diameter) whereas the dose (or number of infective particles in the case of biopesticides ) is a function of their volume.

  8. Hydrodynamic quantum analogs - Wikipedia

    en.wikipedia.org/wiki/Hydrodynamic_quantum_analogs

    A fluid droplet can float or bounce over a vibrating fluid bath because of the presence of an air layer between the droplet and the bath surface. The behavior of the droplet depends on the acceleration of the bath surface. Below a critical acceleration, the droplet will take successively smaller bounces before the intervening air layer ...

  9. Droplet cluster - Wikipedia

    en.wikipedia.org/wiki/Droplet_cluster

    Droplet cluster is a self-assembled levitating monolayer of microdroplets usually arranged into a hexagonally ordered structure over a locally heated thin (about 1 mm) layer of water. The droplet cluster is typologically similar to colloidal crystals .
