1/4 The Solenoidal Vector Field We of course recall that a conservative vector field C ( r ) can be identified from its curl, which is always equal to zero: ∇ x C ( r ) = 0 Similarly, there is another type of vector field S ( r ) , called a solenoidal field, whose divergence is always equal to zero: From the divergence of ∇p−∇2u = 0, using the solenoidal property of u, we see that ∇2p= 0, and hence that ∇4u = ∇2∇2u = 0. The curl of this equation gives also ∇2∇ × u = 0. The components of u thus solves the biharmonic equation ∇4φ= 0 as well as the solenoidal condition, and the vorticity is a harmonic vector field.Influences of compressibility on the balance of solenoidal dissipation rate of turbulent kinetic energy are investigated by means of direct numerical simulations of free and wall-bounded turbulent ...Solenoidal vector field | how to show vector is solenoidal | how to show vector is solenoidalVideo Tutorials,solenoidal vector field,solenoidal vector field,...Magnetic field inside the solenoid.
