Typical Model Studies

Typical Model Studies

Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.

Impact

Impact

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...

Area of Science:

Environmental Science
Fluid Dynamics
Computational Physics

Background:

Multiphase splash phenomena are critical for understanding pollution transport.
Petrol drops impacting water surfaces can lead to environmental contamination.
Previous studies lacked detailed analysis of droplet composition during splashes.

Purpose of the Study:

To numerically simulate and analyze the multiphase splash of a petrol drop on water.
To investigate the scale and composition of petroleum contamination spread during splashes.
To validate numerical models with experimental high-speed imaging data.

Main Methods:

Utilized a 3D multiphase transport model with the multiphaseInterFoam solver (OpenFOAM).
Employed the finite volume method (FVM) for spatial discretization.
Conducted 13 numerical simulations with varying drop sizes and velocities, validated by high-speed camera experiments (2800 fps).

Main Results:

Simulations accurately captured splash dynamics, including cavity spread and jet formation.
Analysis revealed splash droplets were primarily mixtures of water and petrol, or pure petrol.
Quantified the scale of petroleum contamination spread, offering insights beyond experimental limitations.

Conclusions:

Numerical modeling provides an efficient method for simulating three-phase splash phenomena.
Splash events significantly contribute to the spread of petroleum-based pollutants.
The study offers a robust workflow for analyzing complex multiphase fluid interactions and environmental impacts.
