Question

Describe stream and potential functions for doublet flow

Answer 1

The elementary basic plane potential flows include uniform flow, source/sink flow, doublet flow and free vortex flow. ... Hence, the combinations of velocity potential and stream functions of elementary flows will lead to a particular body shape that can be interpreted as flow around that body.

Answer 2

______________________________

In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: So φ can be identified as the velocity potential and ψ is called the stream function.
