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 velocity potential?

For an irrotational flow, there exists a scalar function, such that the velocity is given by the gradient of velocity potential.

How to Calculate Velocity Potential for Uniform Incompressible Flow in Polar Coordinates?

Velocity Potential for Uniform Incompressible Flow in Polar Coordinates calculator uses Velocity Potential = Freestream Velocity*Radial Coordinate*cos(Polar Angle) to calculate the Velocity Potential, The Velocity Potential for Uniform Incompressible Flow in Polar Coordinates states that the function is directly proportional to the radial distance from the origin (r) and the cosine of the angular coordinate (θ), scaled by the velocity of the flow (U). This implies that the value of the velocity potential function increases linearly with radial distance from the origin and varies with the angle's cosine, reflecting the flow's uniform nature and its dependency on the angular direction. Velocity Potential is denoted by ϕ symbol.
