What is uniform flow?

Uniform flow is a flow of a fluid in which each particle moves along its line of flow with constant speed and in which the cross-section of each stream tube remains unchanged.

What is stream function?

The stream function is defined such that ψ= constant is the equation of a streamline, and the difference in the stream function between two streamlines is equal to the mass flow between the streamlines.

How to Calculate Stream Function for Uniform Incompressible Flow?

Stream Function for Uniform Incompressible Flow calculator uses Stream Function = Freestream Velocity*Distance on Y-Axis to calculate the Stream Function, The Stream Function for Uniform Incompressible Flow states that the stream function is directly proportional to the distance from the flow axis and the velocity of the flow, this implies that the value of the stream function increases linearly with distance from the flow axis, reflecting the uniform nature of the flow. Stream Function is denoted by ψ symbol.
