In fluid dynamics, potential flow (or ideal flow) describes the velocity field as the gradient of a scalar function: the velocity potential. As a result, a potential flow is characterized by an irrotational velocity field, which is a valid approximation for several applications. The irrotationality of a potential flow is due … See more Description and characteristics In fluid dynamics, a potential flow is described by means of a velocity potential φ, being a function of space and time. The flow velocity v is a vector field equal to the gradient, ∇, of the … See more Any differentiable function may be used for f.

Web12.2.5 Fractionally associative plastic flow rule. The plastic potential function controls the direction and increment of plastic strain during strain hardening and softening processes, which is expressed as (Malvar & Simons, 1996) (12.15) where σeq is the equivalent stress given in the strength surface; ω is the positive scalar related to ... WebNov 19, 2024 · The notion of a velocity potential in three-dimensions arises when the flow is irrotational. In this case, the curl of the velocity field vanishes (as it would in two-dimensional flow as well), and the velocity field can be expressed in terms of the gradient of a real-valued scalar potential function $$\mathbb{u} = - \nabla \phi.$$ Webirrotationality of the flow field, whereas the stream function is a consequence of conservation of mass. It is to be noted, however, that the velocity potential can be defined for a general three-dimensional flow, whereas the stream function is restricted to two-dimensional flows. For an incompressible flow we know from the conservation of mass: the kiffness
