Squeeze Flow Rheology of Zeolite Suspensions

Aggregation, heterogeneous flows, and complex particle geometries all pose challenges in rheology. This paper uses squeeze flow rheometry techniques to examine a case, where all of these played a role. The applicability of some squeeze theories is tested, and the ability to predict results based on suspension theories is examined. The squeeze flow data is shown to deviate from Stefan's Law [1]. The suspension rheology deviated from predicted theory, but by taking into account particle effects
