| Zusammenfassung |
| A continuum theory is developed for a geophysical fluid consisting of two
species. Balance laws are given for the individual components of the
mixture, modeled as micropolar viscous fluids. The continua allow
independent rotational degrees of freedom, so that the fluids can exhibit
couple stresses and a non-symmetric stress tensor. The second law of
thermodynamics is used to develop constitutive equations. Linear
constitutive equations are constituted for a heat conducting mixture, each
species possessing separate viscosities. Field equations are obtained and
boundary and initial conditions are stated. This theory is relevant to an
atmospheric mixture consisting of any two species from rain, snow and/or
sand. Also, this is a continuum theory for oceanic mixtures, such as water
and silt, or water and oil spills, etc. |
