5.7 Fundamental and Composite Potential Flows
Incompressible flows that can be characterized by potential functions are commonly referred to as potential flows. Two-dimensional potential flows can also be characterized by stream functions, where stream-function contours are streamlines. An attractive feature of potential-flow formulations is that they can be applied to describe flows around solid bodies, because the flow normal to a streamline is equal to zero and hence, any streamline can be taken as coinciding with the surface of a solid body.
5.7.1 Principle of Superposition
The principle of superposition states that if there are multiple solutions to a differential equation that is both linear and homogeneous, then any linear combination ...
