A High-Precision Rotational Rheometer for Temperatures up to 1700 °C

Solid State Phenomena, 2012
Rheometrical analysis of steel slurries in rotational rheometers requires a range of operating temperatures of about 1300 to 1600 °C, leading to a delicate device-related challenge with respect to the applied materials on the one hand and a suitable constructional set-up gaining unbiased measurements on the other hand. Accordingly, a new high-precision

Numerical Simulation of Mixing Polymeric Fluids in Rotating Cylinder Rheometer

2020
In this study, mixing of non-Newtonian polymeric fluids was simulated three dimensionally using a power-law rheological model in a rotational rheometer with coaxial cylinders. The simulation was performed by obtaining 3D components of velocity for each grid point using finite volume method and tracking the grid points in specified time intervals.

Viscous Dissipation in the Flow Between Eccentric Rotating Disks (Orthogonal Rheometer)

Transactions of the Society of Rheology, 1977
The orthogonal rheometer has become increasingly popular for determination of the viscoelastic properties of fluids. Here we present an analytical solution for the steady-state temperature distribution arising from the dissipation due to flow between infinite, isothermal eccentric rotating disks.

Upscaling drag reduction of rotational rheometer to linear pipe flow

Physics of Fluids
Drag reduction (DR) is a phenomenon associated with adding small amounts of drag-reducing agents to reduce friction causing a reduction in the pressure gradient needed for pumping a solution under turbulent conditions. Traditionally, DR has been measured with linear flow devices, such as flow loops.

On the concentration gradient of polymer solution in a rotating rheometer

Journal of Rheology, 1991
The pressure gradient due to the normal stress effect gives rise to a distribution of concentration in the polymer solution flowing in a rotating rheometer. The gradient of concentration in steady state was estimated with a thermodynamic method. It was shown to be proportional to the normal stress difference and inversely proportional to the osmotic ...
