Yield stress fluids in industrial applications
Frigaard, Ian A.
University of British Columbia

Many industrial fluids have non-Newtonian rheological behaviour. Amongst the wide variants in fluid behaviour are those that exhibit a yield stress. We describe these fluids and some of the limitations in their simplest mathematical descriptions. We then outline a range of different problems stemming from the petroleum industry in which these fluids play a key role, giving examples of where mathematical modelling can be effectively used to answer practical questions and where it appears to fall short of experimental reality.
