9. Uniform and Non-Uniform Flows
The chapter explains the concepts of uniform and non-uniform flow, highlighting their definitions and implications. It contrasts uniform flow, where fluid properties remain constant in space, with non-uniform flow, where these properties vary from one point to another. The significance of streamlines and the no-slip condition in fluid mechanics are also discussed, culminating in a practical exercise on evaluating streamlines in a given flow field.

What we have learnt
- Uniform flow occurs when fluid properties are constant throughout space, while non-uniform flow exhibits spatial variations.
- Non-uniform flow can vary in direction along the flow or perpendicular to it and is notably influenced by solid boundaries.
- The concept of streamlines illustrates the relationship between fluid velocity and flow paths in a fluid medium.
Key Concepts
- -- Uniform Flow
- A flow condition where the velocity and other hydrodynamic parameters do not change from point to point in space.
- -- NonUniform Flow
- A flow condition where fluid properties vary from one point to another within the fluid domain.
- -- Streamline
- A continuous line in flow that is tangential to the velocity vector, representing the path followed by fluid particles.
- -- NoSlip Condition
- A principle that states the fluid velocity at a solid boundary is equal to zero, impacting flow characteristics nearby.
