dc.description.abstract | We present a dynamic density functional theory dDFT which takes into account the advection of
the particles by a flowing solvent. For potential flows, we can use the same closure as in the absence
of solvent flow. The structure of the resulting advected dDFT suggests that it could be used for
nonpotential flows as well. We apply this dDFT to Brownian particles e.g., polymer coils in a
solvent flowing around a spherical obstacle e.g., a colloid and compare the results with direct
simulations of the underlying Brownian dynamics. Although numerical limitations do not allow for
an accurate quantitative check of the advected dDFT both show the same qualitative features. In
contrast to previous works which neglected the deformation of the flow by the obstacle, we find that
the bow wave in the density distribution of particles in front of the obstacle as well as the wake
behind it are reduced dramatically. As a consequence, the friction force exerted by the polymer
particles on the colloid can be reduced drastically. | es |
