Abstract
A method of determining one or more bulk rheological properties of a particle laden fluid comprising providing a system comprising a vessel, a pump coupled to the vessel, and a flow-through apparatus coupled to the pump and the vessel, wherein the flow-through apparatus comprises a flow chamber, a bob rotatably disposed within the chamber, wherein the bob comprises an outer geometry adapted for continuous laminar flow in an axial direction, and a gap between the chamber and the bob, pumping the particle laden fluid into the flow-through apparatus, shearing the particle laden fluid within the gap of the flow-through apparatus, and collecting data from the bob and observing the particle laden fluid to determine one or more bulk rheological properties of the particle laden fluid.
