WebArticle - Managing your personal web ... WebThe effect of sample underfill on parallel-plate and cone-plate rheometers is examined. Sample underfill can be caused by incomplete filling of a sample or loss of fluid during a test by, for example, evaporation. It is shown that even a small degree of sample underfill can lead to significant errors in measuring viscosity. A method is proposed to reduce these …

WebThe squeezing of a disc-shaped sample of fluid between parallel plates under the action of a normal force represents a simple, yet extremely useful rheological technique. It has been used for many years, with Stefan [1] solving the relationship between squeezing force and plate separation for squeezing of a Newtonian fluid in 1874.
