Study Notes

Fluid Mechanics Overview

  • Fluid mechanics studies fluids at rest (fluid statics) and in motion (fluid dynamics).
  • Fluid behavior is vital in applications such as engineering, meteorology, and aerodynamics.

Characteristics of Fluids vs. Solids

  • Fluids can flow and conform to the shape of their containers, unlike solids which maintain shape.
  • No-slip condition describes the scenario where fluid in contact with a solid surface has zero velocity relative to that surface.

Classification of Fluid Flows

  • Viscous vs. Inviscid Flow: Viscous flow includes the effects of viscosity, while inviscid flow neglects these effects.
  • Internal vs. External Flow: Internal flow occurs in confined spaces (like pipes), whereas external flow is over surfaces (like air over an airplane).
  • Compressible vs. Incompressible Flow: Compressible flow involves significant density changes (like gases), while incompressible flow assumes constant density (like most liquids).

Characteristics of Incompressible Flow

  • Density remains nearly constant during flow, ensuring the volume of fluid does not change.

Types of Flow Based on Behavior

  • Laminar Flow: Smooth and orderly, characterized by low Reynolds number (Re).
  • Turbulent Flow: Chaotic and irregular, occurring with high Reynolds number; defined by eddies and swirls.

Additional Flow Classifications

  • Natural Flow: Driven by natural forces (e.g., buoyancy effects), such as the rise of warm air.
  • Forced Flow: Achieved by external means (e.g., pumps, fans) to drive fluid movement.
  • Steady Flow: Fluid properties do not change with time at any point in the fluid.
  • Unsteady Flow: Fluid properties vary with time at one or more points.

Uniform vs. Non-Uniform Flow

  • Uniform Flow: Fluid velocity is consistent throughout a flow field.
  • Non-Uniform Flow: Fluid velocity varies at different locations within the flow.

Dimensions and Measurement

  • Quantitative description of fluids necessitates comparative standards for measurements. Both a number and a unit are needed for clarity and communication in scientific contexts.
