We study the transient and steady shear rheology of rigid particle suspensions in Boger fluids via complete 3D numerical simulations and experiments. We calculate the transient per-particle extra viscosity and primary stress coefficients for suspensi

Large amplitude oscillatory shear (LAOS) was performed on non-Newtonian minor phase in Newtonian matrix phase polymer blends as a first step toward understating more complex immiscible polymer blends under high deformation condition. The blend consis
To elucidate the key factor for the quantitative prediction of the shear-thickening in suspensions in viscoelastic fluids, direct numerical simulations of many-particle suspensions in a multi-mode Oldroyd-B fluid are performed using the smoothed prof

The sedimentation of a suspension of rigid spherical particles in a polymeric fluid is studied with experiments and numerical simulations. It is shown that settling in a viscoelastic Boger fluid is time-dependent and inhomogeneous; both experiments a

In this study, we investigated the motion of solid particles dispersed in highly viscous complex fluids agitated in a stirred vessel. We used a refractive index matching method and a combination of planar laser- induced fluorescence (PLIF), particle

Molecular engineering facilitates the development of a complex fluid with contradictory requirements of yield stress and sprayability, while minimizing the amount of structuring material (0.05 wt%). This unique system can be achieved by a biopolymer

The mechanism for shear thickening of the viscometric functions of rigid non-Brownian sphere suspensions in highly elastic fluids is studied numerically. Particular focus is placed on the particle-induced fluid stress, which is the dominant contribut

The steady shear rheology of nondilute suspensions of noncolloidal, rigid spheres in highly elastic, constant viscosity fluids is studied via numerical simulation using three-dimensional, finite-volume methods and via experiments using cone-and-plate

In this paper, the impact dynamics of Boger drops on dry solid surfaces is investigated experimentally. The effects of viscosity, surface wettability, and impact velocity on the spreading and receding behavior of the Newtonian and viscoelastic drops

In this article, we report the post-collision elasto-hydrodynamics of non-Newtonian elastic or Boger fluid droplets [polyacrylamide (PAAM) solution in water] on convex or cylindrical targets of various diameters. Both hydrophilic and superhydrophobic
