WebProblem 2. - For a given flow field, if the velocity components are given by: u = − A e − k y cos (k x); v = A e − k y sin (k x) Where A and k are constants a) Find the stream function for this flow (ψ) b) Find the value of (div V) at all points in the flow field c) Is this flow physically possible as an incompressible flow? why? d ... In fluid dynamics, a flow is considered incompressible if the divergence of the flow velocity is zero. However, related formulations can sometimes be used, depending on the flow system being modelled. Some versions are described below: Incompressible flow: $${\displaystyle {\nabla \cdot \mathbf {u} =0}}$$. This can … See more In fluid mechanics or more generally continuum mechanics, incompressible flow (isochoric flow) refers to a flow in which the material density is constant within a fluid parcel—an infinitesimal volume that moves … See more In some fields, a measure of the incompressibility of a flow is the change in density as a result of the pressure variations. This is … See more As defined earlier, an incompressible (isochoric) flow is the one in which $${\displaystyle \nabla \cdot \mathbf {u} =0.\,}$$ See more • Bernoulli's principle • Euler equations (fluid dynamics) • Navier–Stokes equations See more The fundamental requirement for incompressible flow is that the density, $${\displaystyle \rho }$$, is constant within a small element volume, dV, which moves at the flow velocity u. Mathematically, this constraint implies that the See more An incompressible flow is described by a solenoidal flow velocity field. But a solenoidal field, besides having a zero divergence, … See more The stringent nature of the incompressible flow equations means that specific mathematical techniques have been devised to solve them.
