Parallel-Plate Rheometer Calibration Using Oil and Lattice Boltzmann Simulation



Chiara F. Ferraris, Nicos Martys, M R. Geiker, N V. Muzzatti


The flow in traditional rotational rheometers is well known and rheological parameters such as viscosity can be calculated relatively easily. On the other hand, when the fluid is a suspension that contains particles with a diameter up to 2 mm, these rheometers need to be modified. The distance between the shearing planes need to be larger, and this causes that the flow pattern are not known leading to the inability to correctly compute the viscosity. This paper presents a modified parallel plate rheometer. Experimental measurements on standards oils were conducted to determine a methodology to calibrate the rheometer. The lattice Boltzman methodology was used to simulate the flow in the modified rheometer. These simulations reproduced the experimental results by taking into account the rheometer geometry, thus validating the experimental approach. In addition, these simulations show that small changes in the rheometer design can have a significant impact on the rheological results. An approach to calibrate the rheometer using standards oil is also described.
