The present invention relates generally to systems and processes for improved drag reduction estimation and measurement and more specifically to portable drag reduction analyzers and processes for upscaling drag reduction data for a variety of field applications. A drag reduction parameter AB for the fluid mixture is used for determining drag reduction for a fluid mixture in an oil field or pipeline operation.

A system for testing a rheological behavior of a slurry comprises a first stirring reactor, a second stirring reactor, a material supply pipe, a driving device, and a pressure detection member. The driving device has a first state and a second state. In the first state, the driving device drives a slurry in the first stirring reactor to be outputted to the second stirring reactor. In the second state, the driving device drives the slurry in the second stirring reactor to be outputted to the first stirring reactor. The pressure detection member is used to measure a pressure level in the material supply pipe.

A viscosity sensor for measuring a viscosity of a fluid flowing in a pipe, includes a base made of a flexible material; a bridge made of a rigid material, wherein the bridge is attached to the base to form a microchannel; a pressure sensor formed within the base; and a controller configured to receive a signal indicative of a capacitance change ΔC from the pressure sensor, and to calculate the viscosity of the fluid flowing through the microchannel based on the received capacitance change ΔC.

A rotating extrusion rheometer includes a control monitoring mechanism, a melt extrusion mechanism, a rotating extrusion rheology machine head, a sensor, a drive chain wheel, a coupler and an electric motor. The control monitoring mechanism, the melt extrusion mechanism, the rotating extrusion rheology machine head are sequentially connected. The rotating extrusion rheology machine head is formed by a connecting pipe (1), a flow dividing support (3), a lower machine neck (12), a machine head piece (15), an opening mold (17), an opening-mold driving chain wheel (20), a core bar (21) and a core-bar driving mechanism. The rheology measurement method comprises the steps where some parameter values of the rheometer are collected first, and then the rheological behaviors of the polymer melt in the rotating extrusion process are obtained by performing calculation by means of using the derived formula.

Rheological measurement systems for use with systems including pressurized polymer melts and/or other viscous materials are described. In one embodiment, a rheometer is connected to an associated system with a bent, curved, or bendable tube to permit the rheometer to measure rheological properties in locations where the rheometer could not otherwise be located due to the presence of obstructions. Embodiments including rigid straight tubes for connecting a rheometer to an associated system are also described. In another embodiment, a flow-through rheometer is connected to an industry standard ½-20 thermowell aperture that is typically used for attaching temperature and pressure probes to a vessel containing a viscous material such as an extruder or injection molding system.
