Steady, Laminar Flow Between Parallel Plates01:17

Steady, Laminar Flow Between Parallel Plates

614
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.

Excess Pressure Inside a Drop and a Bubble

2.8K
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.

Couette Flow01:22

Couette Flow

692
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...

Boundary Layer Characteristics01:18

Boundary Layer Characteristics

357
When a fluid encounters a solid surface, a boundary layer forms due to the interaction between the fluid's motion and the stationary surface. This phenomenon is characterized by a thin region adjacent to the surface where viscous forces dominate, influencing the fluid's velocity profile. The development of the boundary layer begins at the leading edge of the surface and evolves as the fluid moves downstream.As the fluid flows over the surface, friction between the fluid and the wall slows down...

Application of the Linear Momentum Equation

300
The application of the linear momentum equation can be used to analyze the forces needed to hold a 180-degree pipe bend in place with flowing water. In this case, water flows through the bend with a constant cross-sectional area of 0.01 square meters and a flow velocity of 15 meters per second. The pressure at the entrance is 0.2 Megapascals and the pressure at the exit is 0.16 Megapascals.
The goal is to determine the force components in the x and y directions to hold the pipe in place. Since...

Speed of Sound in Solids and Liquids

3.6K
Most solids and liquids are incompressible—their densities remain constant throughout. In the presence of an external force, the molecules tend to restore to their original positions, which is only possible because the constituents interact. The interactions help the constituents pass on information about external disturbances, like sound waves. Therefore, sound waves travel faster through these media. Compared to solids, the constituents in a liquid are less tightly bound. Thus, sound...

Area of Science:

  • Thermodynamics
  • Materials Science
  • Physical Chemistry

Background:

  • The Young-Laplace equation is typically applied to fluid-fluid interfaces.
  • Applying it to solid-liquid interfaces presents challenges in defining pressure and interfacial free energy.
  • Previous studies suggest discrepancies in pressure definitions for solid-liquid systems.

Purpose of the Study:

  • To investigate the application of the Young-Laplace equation to solid-liquid interfaces.

  • To reconcile simulation results with established thermodynamic principles.

Main Methods:

  • Utilizing computer simulations of hard sphere systems to model solid clusters in a liquid.
  • Analyzing the pressure difference between the solid cluster and the external liquid.
  • Applying Gibbsian thermodynamics to define interfacial free energy using appropriate pressure terms.

Main Results:

  • Computer simulations indicate lower internal pressure within solid clusters compared to the external liquid pressure.
  • This pressure difference initially suggests a negative interfacial free energy.
  • Using the thermodynamic pressure, as proposed by Tolman, results in a positive interfacial free energy.
  • The calculated positive interfacial free energy values align well with prior nucleation study results.

Conclusions:

  • The distinction between mechanical and thermodynamic pressure is crucial for solid-liquid interfaces, unlike fluid-fluid interfaces.
  • The correct application of Gibbsian thermodynamics requires the use of thermodynamic pressure for curved solid-liquid interfaces.
  • This approach resolves discrepancies and provides accurate interfacial free energy values, supporting Gibbs' hypothesis.
