Excess Pressure Inside a Drop and a Bubble01:13

Excess Pressure Inside a Drop and a Bubble

3.5K
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.

Cell Motility through Blebbing

1.9K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Rise of Liquid in a Capillary Tube01:18

Rise of Liquid in a Capillary Tube

3.1K
When very thin cylindrical tubes, called capillaries, are dipped in a liquid, the liquid rises or falls in the tube compared to the surrounding liquid. This phenomenon is called capillary action. Capillary action occurs due to the combination of two opposing forces: the cohesive forces of the liquid, which cause it to stick to itself and form a rounded shape, and the adhesive forces between the liquid and the walls of the container, which cause the liquid to be attracted to the container walls.

Couette Flow01:22

Couette Flow

1.4K
Couette flow represents the flow of fluid between two parallel plates, with one plate fixed and the other moving with a constant velocity. This configuration allows for a simplified analysis using the Navier-Stokes equations, which govern fluid motion under conditions of viscosity and incompressibility. For Couette flow, the assumptions include a steady, laminar, incompressible flow with a zero-pressure gradient in the flow direction. This flow type is beneficial for understanding shear-driven...

Bioreactor Controls-II

74
In aerobic fermentations, oxygen is vital for microbial growth and metabolite production. Since air comprises only about 20% oxygen and the gas is poorly soluble in water—just 9 ppm at 20°C—supplying sufficient oxygen becomes a critical challenge, especially in high-demand processes like yeast growth or citric acid production. Even a fully saturated broth may offer only a few seconds of oxygen availability.To address this, sterile or scrubbed air is introduced into the...

Steady, Laminar Flow Between Parallel Plates01:17

Steady, Laminar Flow Between Parallel Plates

1.1K
Understanding steady, laminar flow between parallel plates is essential for analyzing and designing flow in narrow rectangular channels, commonly found in various water conveyance and drainage systems. The Navier-Stokes equations govern fluid motion and are generally challenging to solve due to their nonlinearity. However, simplifications are possible in certain cases, like the steady laminar flow between parallel plates. For this scenario, we assume steady, incompressible, laminar flow.

Summary
This summary is machine-generated.

Researchers discovered that rubbing solids in liquid creates bubbles. Bubble formation depends on surface properties and requires exceeding specific force and velocity thresholds, offering potential for controlled bubble patterns.

Area of Science:

  • Surface science and tribology
  • Fluid dynamics and bubble nucleation

Background:

  • Bubble formation during solid-liquid interactions is not fully understood.
  • Understanding nucleation mechanisms is crucial for various applications.

Purpose of the Study:

  • To investigate the nucleation and growth of bubbles during the rubbing of solids in a liquid.
  • To identify the key parameters influencing bubble formation.

Main Methods:

  • Experimental observation of bubble nucleation during rubbing.
  • Analysis of surface topography using atomic force microscopy (AFM) and scanning electron microscopy (SEM).

Main Results:

  • Bubble nucleation is strongly dependent on material properties and surface roughness.
  • A threshold of rubbing force and velocity is required for sustained bubble trail formation.
  • Microscopic bubbles originate from gas pockets formed by the fracturing of surface asperities.

Conclusions:

  • Surface asperity fracturing, potentially enhanced by chemical reactions, is the source of microscopic gas pockets.
  • Findings provide insights into preventing unwanted bubble formation and enabling controlled bubble pattern generation ('writing with bubbles').
