Circumstantial evidence in support of bivelocity hydrodynamic theory for mixtures.
Based upon findings with respect to the viability of the expression j(v)=-rhoD(v)nablav hypothesized to represent the constitutive equation for the diffusive volume flux in ideal binary mixtures (rho=mass density, v=1/rho=specific volume, and D(v)=volume diffusion coefficient), implicit evidence is offered in support of the recently developed theory of bivelocity continuum hydrodynamics for mixtures. Present findings for the case of mixtures add to existing evidence already available for the single-component case, thus supporting the viability of bivelocity hydrodynamic theory in general.
