Fluid Pressure over Curved Plate of Constant Width01:12

Fluid Pressure over Curved Plate of Constant Width

1.6K
When a curved plate of constant width is submerged in a liquid, the pressure acting normal to the plate varies continuously both in magnitude and direction. Calculating the magnitude and location of the resultant force at a point is often challenging for such cases. One of the methods to determine the resultant force and its location involves separately calculating the horizontal and vertical components of the resultant force. This complex calculation can be simplified by representing the...

Viscosity

5.9K
When water is poured into a glass, it falls freely and quickly, whereas if honey or maple syrup is poured over a pancake, it flows slowly and sticks to the surface of the container. This difference in the flow of different kinds of liquids arises due to the fluid friction between the liquid layers and the liquid and the surrounding material. This property of fluids is called fluid viscosity. In this example, water has a lower viscosity than honey and maple syrup.
The SI unit of viscosity is...

Laminar and Turbulent Flow

8.6K
Fluid dynamics is the study of fluids in motion. Velocity vectors are often used to illustrate fluid motion in applications like meteorology. For example, wind—the fluid motion of air in the atmosphere—can be represented by vectors indicating the speed and direction of the wind at any given point on a map. Another method for representing fluid motion is a streamline. A streamline represents the path of a small volume of fluid as it flows. When the flow pattern changes with time, the...

Capillarity in Fluid01:19

Capillarity in Fluid

276
Capillarity describes the movement of liquid in small spaces without external forces acting on it. The capillarity is driven by surface tension and adhesive interactions between the liquid and surrounding solid surfaces. This effect is often seen in narrow tubes, porous materials, and fine particles.
Surface tension is crucial to capillarity. It results from cohesive forces between liquid molecules at the liquid-air boundary, forming a skin that resists external forces. When the capillary tube...

Couette Flow01:22

Couette Flow

338
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...

Newtonian Fluid: Problem Solving01:18

Newtonian Fluid: Problem Solving

272
Newtonian fluids exhibit a constant viscosity, meaning their shear stress and shear strain rate are directly proportional. This property ensures a predictable and stable response to applied forces, maintaining a linear relationship between force and flow. Examples include water, air, and light oils, consistently demonstrating this proportional behavior regardless of external conditions.
A velocity gradient forms within the fluid when a Newtonian fluid is placed between two parallel plates, with...

    Summary

    Surface curvature enhances epithelial fluidization and collective cell migration during the unjamming transition (UJT). Increased curvature promotes tissue malleability in smaller epithelial structures, which become more rigid with growth.

    Area of Science:

    • Biophysics
    • Developmental Biology
    • Cell Biology

    Background:

    • Epithelial layers transition from quiescent to migratory states for tissue repair and development.
    • The unjamming transition (UJT) drives epithelial fluidization and collective cell migration.
    • Existing models often overlook the impact of surface curvature on the UJT.

    Purpose of the Study:

    • To investigate the influence of surface curvature on tissue plasticity and cellular migration.
    • To explore the UJT in epithelial layers on curved surfaces.

    Main Methods:

    • Utilized a vertex model simulation.
    • Embedded the model on a spherical surface to represent varying curvatures.

    Main Results:

  • Increasing surface curvature facilitates the UJT by lowering energy barriers for cellular rearrangements.
  • Higher curvature enhances cell intercalation, mobility, and self-diffusivity.
  • Epithelial structures exhibit increased malleability and migration at higher curvatures, becoming more rigid as they enlarge.

    • Conclusions:

    • Surface curvature is a critical factor influencing epithelial tissue plasticity and collective cell migration.
    • Findings provide a framework for understanding how geometry, cell shape, and propulsion impact tissue remodeling and stabilization.
    • Curvature-driven changes in the UJT are essential for dynamic tissue processes in vivo.
