This technology uses a novel vane cross-sectional structure and detachable textured sample container to measure flow properties of yield stress fluids with high accuracy. This rheometric instrumentation, used in conjunction with a standard rheometer, can improve the process of analyzing yield stress fluids in a range of industrial, commercial, and academic settings. The technology has significant applications in a wide variety of consumer goods (e.g., toothpaste, cosmetics, ketchup), construction products (e.g., cement), and also in the field of oil/gas exploration (drilling muds and fracking fluids).
