Steady, Laminar Flow Between Parallel Plates01:17

Steady, Laminar Flow Between Parallel Plates

642
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.

Newtonian Fluid: Problem Solving

712
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...

Couette Flow

714
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...

Steady, Laminar Flow in Circular Tubes

762
Hagen-Poiseuille flow describes a viscous fluid's steady, incompressible flow through a cylindrical tube with a constant radius R. This flow profile is often applied to understand fluid transport in narrow channels, such as capillaries. It serves as a foundational example of laminar flow. In this model, cylindrical coordinates (r,θ,z) are used to describe the radial (r), angular (θ), and axial (z) dimensions within the tube. For Hagen-Poiseuille flow, the velocity profile is purely axial,...

Viscosity01:17

Viscosity

6.9K
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...

Uniform Depth Channel Flow01:27

Uniform Depth Channel Flow

416
Uniform depth channel flow keeps fluid depth consistent along channels such as irrigation canals. In natural channels, such as rivers, approximate uniform flow is often assumed. This condition occurs when the channel’s bottom slope matches the energy slope, balancing potential energy lost from gravity with head loss due to shear stress. This balance prevents depth changes along the channel length, resulting in a steady, uniform flow.Uniform flow in open channels with a constant cross-section...

  • Materials science
  • Physical chemistry

Background:

  • Nanoparticle (NP) transport in subsurface environments is vital for environmental risk assessment and material applications.
  • Existing research shows conflicting data on how fluid flow velocity affects NP attachment efficiency.

  • To develop a novel method for observing NP deposition mechanisms in real-time.
  • To investigate the influence of fluid flow velocity on NP attachment efficiency.
  • To elucidate the physical processes governing NP behavior in subsurface environments.

Main Methods:

  • Utilized quartz crystal microbalance with dissipation monitoring (QCM-D) to separate and monitor NP deposition mechanisms.
  • Measured in situ, real-time particle diffusion from bulk liquid to solid surface.
  • Analyzed the effect of varying fluid flow velocities on NP deposition and attachment.

Main Results:

  • Verified that NP diffusion velocity increases with fluid flow velocity, enhancing kinetic energy and influencing deposition.
  • Observed a decrease in secondary minimum deposition and an increase in primary minimum deposition with rising flow velocity.
  • Demonstrated that NPs deposited at the primary minimum exhibit greater resistance to hydrodynamic forces, leading to higher attachment efficiencies.
