| Abstract: | We present a new development in fluid theory, incorporating into it the velocity and spin fields; special attention is given
to the structure of transport.The theory includes asymmetric molecular stresses and independent rotation velocity, i.e., spin. Our approach is based on our former studies on the asymmetric continuum theory with the balance and constitutive laws
for displacement velocity and independent rotation motion, and points out the role of a related characteristic length unit.
It is assumed that the vorticity caused by velocities can induce a spin transport counterpart. Thus, under certain conditions,
an additional transport term due to rotational velocity fields may be incorporated to the velocity transport, which may lead
to the vortex fields included directly into the theory. |
