What we have learnt
- The continuity equation demonstrates the principle of mass conservation in fluid flow.
- Fluid motion can be classified as rotational or irrotational based on the presence of angular velocity.
- The stream function and potential function are key tools in analyzing fluid behaviors in two-dimensional flows.
Key Concepts
- -- Continuity Equation
- A mathematical expression that describes the conservation of mass within a fluid system expressed as A1V1 = A2V2.
- -- Rotational Motion
- Fluid motion characterized by non-zero angular velocity components along any axis.
- -- Stream Function
- A function that remains constant along streamlines in a flow field, helping to analyze two-dimensional flows.
- -- Potential Function
- A scalar function whose gradient gives the velocity field in an irrotational flow, satisfying Laplace's equation.
- -- Vorticity
- A measure of local rotational motion of a fluid particle, represented as twice the angular velocity.
