Hydrodynamic interactions on dilute solutions of spherical beads under shear flow are calculated with the method of induced forces. The Navier-Stokes equation is considered in the Stokes approximation. Hydrodynamic interactions cause the drag to be anisotropic in space. Numerical solutions are obta
## Abstract **Summary:** Polymer orientation in dilute solutions undergoing shear flow is investigated computationally by means of the Brownian dynamics simulation technique applied to the beadβspring chain model. The dependence of the degree of orientation on the shear intensity is evaluated throu
Abstrac~The inception of adiabatic steady shear flow of a dilute polymer solution modeled as Hookean dumbbells is considered. The effects of temperature variations in the flow are included explicitly in the constitutive equation. These temperature variations are caused in the flow by the conversion
A systematic framework introduced recently to obtain parameter-free predictions of material properties of dilute polymer solutions in extensional ows is reviewed. The essential constraint of ensuring that the model polymer molecule has a ΓΏnite length is met by using a bead-spring chain model with ΓΏn
