ABSTRACT:
Testing of rheological properties of a fluid is performed between a pair of members having cooperating faces, each characterized by minute, randomly interspersed land portions and cavity portions. The land portions of each face are planar and are disposed geometrically in a common plane. The cavity portions are irregular and are disposed in a network subordinate to the common plane. Testing involves the steps of placing a sample of the fluid between the cooperating faces, pressing the cooperating faces into flush contact with each other, and pulling the cooperating faces from each other. The force required for rupture of the fluid within itself, without first breaking its contact with the cooperating faces, is a function of the shear stress, yield point and other rheological properties of the fluid.
