Stokes Law: Understanding Viscous Drag on Small Particles

Stokes Law, derived by Sir George Gabriel Stokes in the 19th century, provides valuable insights into the behavior of small particles suspended in a fluid. This law specifically focuses on the calculation of viscous drag force acting upon these particles.

The law states that the drag force experienced by a small sphere moving through a viscous medium is directly proportional to its velocity and radius, as well as the viscosity of the fluid. Mathematically, it can be expressed as:

Fd = 6πηrv

  • Fd: Drag force acting on the particle
  • η: Viscosity of the fluid
  • r: Radius of the particle
  • v: Velocity of the particle

Stokes Law assumes laminar flow conditions, where the fluid moves smoothly in parallel layers without turbulence. It is applicable to particles with small sizes relative to the mean free path of the molecules in the fluid.

This law finds significant applications in various fields, including physics, chemistry, engineering, and biology. It helps in understanding the settling behavior of particles in sedimentation processes, the motion of microorganisms in fluids, and the design of filtration systems.

Moreover, Stokes Law serves as the foundation for the measurement of particle size using techniques like sedimentation analysis and dynamic light scattering.

Stokes Equation: An Overview of a Fundamental Fluid Dynamics Equation

The Stokes equation, named after Irish mathematician George Gabriel Stokes, is a fundamental partial differential equation that describes the motion of a viscous fluid. It serves as a cornerstone in fluid dynamics and finds applications in various fields, including physics, engineering, and biology.

The equation itself embodies the principles of conservation of mass and linear momentum. It relates the velocity field of a fluid to the pressure gradient and the viscous forces within the fluid. The Stokes equation is derived from the more general Navier-Stokes equations, which include additional terms to account for non-ideal or turbulent flows.

Mathematically, the two-dimensional form of the Stokes equation can be expressed as:

∇²v = ∇2???? + ∇(????/????)
∇ ⋅ ???? = 0
  • ∇² represents the Laplacian operator (∂²/∂????² + ∂²/∂????²) that measures the spatial variation of the velocity vector ????.
  • ???? denotes the velocity vector field of the fluid.
  • ???? corresponds to the pressure distribution within the fluid.
  • ???? symbolizes the dynamic viscosity of the fluid.

The first equation states that the Laplacian of the velocity field is equal to the sum of the Laplacian of the pressure field and the gradient of pressure with respect to viscosity. This relationship describes how the fluid’s internal forces affect its motion.

The second equation represents the incompressibility condition, stating that the divergence of the velocity field is zero. In other words, it implies that the fluid cannot be compressed or expanded in the absence of external forces.

Solving the Stokes equation allows researchers and engineers to analyze various fluid flow scenarios, such as the behavior of viscous fluids in pipes, the flow around solid objects, or the movement of microorganisms in liquids. The equation provides insights into important phenomena like drag forces, boundary layer formation, and flow separation.

While the Stokes equation has limitations for highly turbulent flows, it remains a valuable tool for understanding fluid mechanics in many practical situations where the fluid motion can be considered laminar or near-laminar.

In summary, the Stokes equation serves as a fundamental mathematical description of the motion of viscous fluids. It combines conservation principles with differential equations to relate the fluid’s velocity and pressure fields to its internal forces. With applications in diverse fields, this equation plays a crucial role in studying fluid dynamics and understanding various phenomena encountered in real-world fluid systems.

Understanding Stokes Shift

The Stokes shift is a phenomenon observed in spectroscopy that refers to the difference in wavelength between the absorption and emission of light by a substance. It is named after Irish physicist Sir George Gabriel Stokes, who first described this effect in the 19th century.

In simple terms, when a substance absorbs energy in the form of light at a particular wavelength, it undergoes an electronic transition. This absorbed energy excites the electrons within the substance to higher energy levels. However, when these excited electrons return to their original state, they release the excess energy as light of a longer wavelength than the absorbed light.

This shift towards longer wavelengths is known as the Stokes shift. It occurs due to various factors, such as relaxation processes, molecular vibrations, and interactions with surrounding molecules. The Stokes shift is commonly observed in fluorescence and phosphorescence spectroscopy, where the emitted light has lower energy and longer wavelength than the incident light.

The magnitude of the Stokes shift can vary depending on the specific properties of the substance and its environment. It is often used to characterize and identify different materials, as each substance exhibits a unique Stokes shift pattern.

In scientific research and applications, understanding the Stokes shift is crucial for studying the behavior of molecules, determining the energy states of materials, developing new sensors or imaging techniques, and investigating photophysical properties.
