Impact01:30

Impact

137
Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...

Laminar and Turbulent Flow01:07

Laminar and Turbulent Flow

8.5K
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...

Accelerating Fluids

1.0K
When a fluid is in constant acceleration, the pressure and buoyant force equations are modified. Suppose a beaker is placed in an elevator accelerating upward with a constant acceleration, a. In the beaker, assume there is a thin cylinder of height h with an infinitesimal cross-sectional area, ΔS.
The motion of the liquid within this infinitesimal cylinder is considered to obtain the pressure difference. Three vertical forces act on this liquid:

Steady Flow of a Fluid Stream01:27

Steady Flow of a Fluid Stream

275
Consider a control volume, such as a pipe with solid boundaries, through which fluid flows and changes direction due to the impulse exerted by the resulting force from the pipe walls. In steady flow, the mass of fluid entering the control volume at a given time, t, with velocity v1, is equal to the mass leaving after infinitesimal time dt, with velocity v2.
During this process, the momentum of the fluid within the control volume remains constant over the time interval dt. By applying the...

Excess Pressure Inside a Drop and a Bubble01:13

Excess Pressure Inside a Drop and a Bubble

1.6K
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.

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model01:09

Theories of Dissolution: The Danckwerts' Model and Interfacial Barrier Model

278
Various dissolution theories provide insight into the factors that influence the dissolution rate. Danckwerts' Model suggests that turbulence, rather than a stagnant layer, characterizes the dissolution medium at the solid-liquid interface. In this model, the agitated solvent contains macroscopic packets that move to the interface via eddy currents, facilitating the absorption and delivery of the drug to the bulk solution. The regular replenishment of solvent packets maintains the...

Area of Science:

  • Fluid Dynamics
  • Interfacial Phenomena
  • Multiphase Flow

Background:

  • Droplet impact on liquid surfaces is a common phenomenon with applications in various industries.
  • Understanding interfacial dynamics is crucial for controlling outcomes like splashing or sealing.
  • Previous studies have focused on single-phase or simpler liquid-liquid interactions.

Purpose of the Study:

  • To investigate the interfacial dynamics during the impact of a core droplet on an interfacial shell liquid layer.
  • To analyze the formation and evolution of air cavities and interfacial liquid columns.
  • To determine the factors influencing the sealing dynamics (deep seal closure vs. no-seal closure).

Main Methods:

  • Experimental study of droplet impact on a liquid-liquid system.
  • Varied impact Weber numbers and interfacial shell liquid volumes.
  • High-speed imaging to resolve cavity expansion, contraction, and liquid thinning.

Main Results:

  • Core droplet impact dragged interfacial liquid, forming a column with an air cavity.
  • Cavity dynamics involved expansion, rapid contraction, and interfacial liquid thinning.
  • Necking dynamics were governed by viscous dissipation, interfacial pull, and core drop inertia.
  • Transition from inertia-dominated to inertia-capillary-dominated deep seal closure observed.
  • No-seal closure occurred at high interfacial liquid volumes and low spread.

Conclusions:

  • The study elucidates the complex interplay of forces governing droplet impact on liquid-liquid interfaces.
  • Interfacial liquid volume, spread, and impact parameters (Weber number) critically influence sealing outcomes.
  • Findings provide insights into controlling interfacial mixing and sealing in immiscible fluid systems.
