WebExamples of simple flow patterns are shown in Figure 1.48 with the equations to their stream functions and velocity potentials. A source is mathematically a point at which fluid appears and flows radially outwards. A sink is a negative source at which fluid flows radially inwards to disappear at a point (similar to the plug hole in a domestic sink, where, … WebJul 15, 2024 · The value of a stream function is that it takes two functions u ( x, y, t) and v ( x, y, t) and replaces them with one higher order function ψ ( x, y, t). This relationship holds for 2-D flow, whether steady or not. And, the substitution of the stream function into the continuity equation only applies spatially to u and v.
