Three Experiments on Complex Fluids
… contributions to the heat transport in a simple model of this system. Our results indicate that convective heat transport is of the same order of magnitude as conductive transport under conditions typical of MRI device tests. The second project is an investigation of the start-up flow and …

Liquefaction and ring shear device
… and that the data can be interpreted using the Herschel-Bulkley model. This model implies that shearing resistance increases with strain rate, but that the increase diminishes in an exponential fashion (i.e. flattens out) at high strain rates. Finally, data were compared with results from other …

Rheology of bubbly liquids containing a non-Newtonian continuous phase
… with respect to bubble break-up. Original models accounting for the process geometry were proposed and found to provide a good description of the aeration process. These models provided insight into the mechanisms taking place during whisking, specifically entrainment and disengagement of …

Development of Closomer And MIBG based Nanoformulation: Application to HIV Prevention and Neuroblastoma Therapy
… behavior with a flow index of 0.93. The Herschel-Bulkley model showed a significant fitting to all experimental data (R² > 0.95). These data suggest that the Closomer-based gels have the desired rheological behavior, with lower complex modulus, and can be a promising platform used for …

Experimental and Analytical Investigation of Particle Dynamics in Newtonian and non-Newtonian Fluids in a Taylor-Couette Cell
… fluids (CMC and Carbomer) are used as a base model for real DF to observe the behavior of particle sedimentation under shear conditions in a controlled environment.</p> <p>Particle Image Velocimetry (PIV) and Manual Particle Tracking (MPT) are employed to assess how rotational speeds and …

Effects of plasticizers on extrusion of PVC: an experimental & numerical study
… below 160 °C and this fact was made use of in modeling the solids conveying zone as a fluid with yield stress. Correlation was established between the viscosities and the extrusion behavior of the plasticized PVC compounds. It was observed that the DIDP plasticized mixes had higher viscosities, …

A motion of freely oscillating droplet of a yield stress fluid: analysis and numerical studies
… small-amplitude oscillations of a droplet of Herschel-Bulkley fluid under the action of surface tension forces. Under certain assumptions it is shown that the finite stopping time $T_f$ of oscillations exists once the yield stress parameter is positive and the flow index $\alpha$ satisfies …
