Rotational Viscometry, can be effected in a fluid contained between two infinite parallel plates by fixing one and moving the second parallel to the first at a fixed speed. The shear rate is defined to be the plate velocity, ., divided by the gap spacing, . Of the six components of the symmetric stress tensor, four are n

Normal Stress Differences from Hole Pressure Measurements,iewed from the hole base (Fig. 11.1). For the particular case of creeping flow of a Newtonian liquid past the mouth of a transverse slot,1 the local stream surfaces are symmetric with respect to reflection in the hole center plane (Figs. 11.1, 11.6(a)). As the Reynolds number Re is increased from ze

Mathematical Modelling of Two-Phase Flows,e in which the suspension is flowing, it is possible to treat the suspension as a homogeneous fluid having specific rheological properties, which can be investigated with classical experimental means. Owing to the number of parameters that may influence the rheology (particle concentration, size, ge
