  1. Fluid flow with no vorticity in it
    In fluid dynamics, potential flow or irrotational flow refers to a description of a fluid flow with no vorticity in it. Such a description typically arises in the limit of vanishing viscosity, i.e., for an inviscid fluid and with no vorticity present in the flow.

    What is the irrotationality of a potential flow?
    The irrotationality of a potential flow is due to the curl of the gradient of a scalar always being equal to zero. In the case of an incompressible flow the velocity potential satisfies Laplace's equation, and potential theory is applicable. However, potential flows also have been used to describe compressible flows and Hele-Shaw flows.

    What is irrotational flow?
    The flow is two-dimensional and the airfoil has infinite span. In fluid dynamics, potential flow or irrotational flow refers to a description of a fluid flow with no vorticity in it. Such a description typically arises in the limit of vanishing viscosity, i.e., for an inviscid fluid and with no vorticity present in the flow.

    What is incompressible irrotational flow?
    An incompressible flow which is inviscid and irrotational is called the potential flow. Note that, the irrotationality is a valid approximation for several flow field applications. Recall, the irrotationality condition of a potential flow, given by Eq. (3.158), is

    Is irrotational fluid a real fluid?
    This is not true in a real, or viscous, fluid. Viscosity prevents the fluid velocity from becoming infinite at the vortex core and causes the core rotate as a solid body. The flow in this core region is no longer considered irrotational. Outside of the viscous core potential flow can be considered acceptable.

    What is U % in irrotational flow?
    ! u = ? = = % . Let us derive u . Since the flow is considered irrotational, all components of the vorticity vector must be zero. The vorticity in cylindrical coordinates is ! , ! u = 0 (for 2D flow). Since the vortex is 2D, the z-component of velocity and all derivatives with respect to z are zero.

    What is the difference between irrotational flow and Vortex?
    Among them, the uniform flow and the doublet are irrotational at all the points in the flow field, while, the vortex contains infinite vorticity at the origin. If we choose an arbitrary curve which does not enclose the origin, then Eq. (4.140) will lead to \ (\mathrm {\Gamma =0}\).
