The most basic introduction to mechanics requires vector concepts
... That is: the divergence of a vector field at a point r is defined as the limit as the enclosed volume approaches zero of the integral of the outward directed normal component of the vector over a closed surface that encloses the point r divided by the volume enclosed, or, in other words, as the limi ...

If there is no force in a direction, there is no friction in the opposite direction. There are two main ki ...

Turbulent transport coefficients and residual energy in mean
... The third and fourth terms on the right-hand side of Eq. 共18兲 represent the cross-helicity dynamo. In the TSDIA analysis, the expressions for the transport coefficients appearing in Eq. 共18兲 are first derived in the wavenumber space; the forms of ␥ and ␥F are slightly different from each other.
