In fluid mechanics, the velocity potential is a scalar quantity that represents the potential energy of a fluid flowing in a potential field. It is related to the fluid’s velocity by the equation:
v = -grad(phi)
where v is the fluid velocity and phi is the velocity potential.
The velocity potential can be used to find the velocity of a fluid at any point in space and time. It is often used in conjunction with the stream function to solve problems in fluid dynamics.
The velocity potential is also known as the stream function in two-dimensional flow. In three-dimensional flow, the stream function is a vector quantity that represents the flow of a fluid in a three-dimensional space.
