However, at pre-asymptotic times it is considerably more difficult to accurately quantify these effects by an effective dispersion coefficient as spreading and mixing are not the same (but intricately related).
Thus, for a better method of dispersibility confirmation, a more effective dispersion analysis technique is required.
Both effects are combined to an effective dispersion model with a single dimensionless parameter, which is a function of pore geometry, axial velocity and molecular diffusion coefficient.
I quantify longitudinal dispersive mixing by the longitudinal effective dispersion coefficient of a conservative tracer introduced by a point-like injection [Water Resour. Res. 36 (120002000) 3591 3604].
It is shown that the spatial distribution of the permeability has a very strong effect on the dynamic behavior of a landfill, whereas mechanical dispersion, manifested by effective dispersion coefficients that depend on the flow velocities, has virtually no effect.
Dispersive mixing can be parameterized by so-called effective dispersion coefficients for a point-like injection even though the plume itself is extended.
Moreover, effective dispersion, relative dispersion slope, birefringence and confinement loss are also presented and discussed.
Moreover, effective dispersion and nonlinear coefficient are also presented and discussed.
The permeability of the blood vessels increases the effective dispersion at the inlet.
For the calculations on the kriged fields, the corresponding conditional covariance is substituted into the analytical expressions of effective dispersion, yielding a correction effective dispersion coefficient.
The hybrid materials showed effective dispersion of BaTiO3 nanoparticles in the PI matrix and favorable thermal properties.
