Types of Fluids

649
Fluids can be classified into Newtonian and non-Newtonian fluids based on their response to shear stress. Newtonian fluids have a linear relationship between shear stress and the shear strain rate, following Newton's law of viscosity. Their viscosity remains constant regardless of the shear rate, making their behavior predictable and easier to analyze. Common examples include water, air, oil, and gasoline.
In contrast, non-Newtonian fluids do not follow Newton's law of viscosity, and...

Viscosity of Fluid01:19

Viscosity of Fluid

903
Viscosity measures the resistance a fluid offers to flow and deformation. It results from internal friction between layers of fluid moving relative to one another. Dynamic viscosity, denoted by the Greek letter mu (μ), quantifies the force needed to move one fluid layer over another. For Newtonian fluids like water and air, the relationship between the shearing stress and the rate of shearing strain is linear, meaning their viscosity remains constant regardless of the applied stress.

Newtonian Fluid: Problem Solving

650
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...

Area of Science:

  • Fluid dynamics
  • Chemical engineering
  • Interface science

Background:

  • Displacing viscous fluids with less viscous ones often leads to interfacial instabilities like digitations.
  • These instabilities cause fluid mixing, hindering efficient displacement and process control.

Purpose of the Study:

  • To propose and numerically investigate a novel protocol for enhancing viscous fluid displacement.
  • To address the challenge of interfacial digitations and fluid mixing during displacement processes.

Main Methods:

  • Numerical simulation of fluid dynamics equations governing the displacement process.
  • Introduction of a chemically active interface between the two fluids.
  • Analysis of parameters influencing the viscosity at the interface.

Main Results:

  • The chemically active interface creates a high-viscosity region, stabilizing the displacement front.
  • Suppression of interfacial digitations was observed, leading to more controlled fluid movement.
  • Optimization of parameters demonstrated a significant improvement in displacement efficiency.

Conclusions:

  • A chemically active interface strategy effectively suppresses interfacial instabilities in viscous fluid displacement.
  • Numerical simulations confirm the protocol's potential for optimizing displacement efficiency in various applications.
  • This method offers a promising approach for controlled fluid manipulation in challenging scenarios.
