Leszek Kulisiewicz, Antonio Delgado
High-pressure rheological measurement methods: A review
Appl. Rheol. 20:1 (2010) 13018 (15 pages) ►

A review of rheological in situ measurement techniques applied to liquids and soft solids at high pressures of more than 100 MPa is presented.The instruments reported in the literature fall into four groups: concentric cylinder rheometers, falling body and rolling ball viscometers, capillary viscometers and oscillatory systems. The measurement techniques are classified with respect to the possibility of carrying out an absolute measurement. Some typical experimental problems and error sources connected with high-pressure conditions are outlined and briefly discussed. The majority of the measurement techniques described in the literature are designed for the determination of the dynamic shear viscosity or viscosity function and only a few contributions report on the development of devices for the determination of other rheological parameters, e.g. normal stress differences or viscoelastic moduli.
