摘要： This invention relates to a method of measuring a rheological property of a composite filled with particles, and evaluation equipment, in which in situ measurement is performed of the rheological property of a composite filled with particles obtained by mixing a particulate material as raw material with a liquid material, in a condition with the original material structure maintained, without destroying the material by applying external force such as shearing force thereto, comprising a step of measuring the coagulation structure of the particulate material within the composite filled with particles as an anisotropy signal, and a step of employing the amount of this anisotropy as an index of the rheological property value of the composite.

摘要： An apparatus and method for determining the viscosity of a fluid over plural shear rates caused by a decreasing pressure differential by monitoring the movement of the fluid through a riser tube and a capillary tube. The movement can be monitored by detecting the changing weight of the fluid, using a precision balance or load cell, as it moves through the riser tube and capillary tube into a fluid collector; or, alternatively, the movement can be monitored by detecting the changing level of a fluid column in the riser tube using a column level detector. A processor then uses the changing weight or height data, along with the dimensions of the capillary tube and a dimension of the riser tube, to determine the viscosity of the fluid. In addition, apparatus and methods for determining fluid viscosity online and fluid mixture homogeneity online are also described.

摘要： A method and apparatus for determining the propensity of fuel materials to leave deposits in compression ignition engines is disclosed. The apparatus consists of a closed chamber fitted with conduits to supply fuel composition, air, and other test fluids to its interior, and arranged to contain or substantially contain a substrate. Substrate is placed in the chamber to provide interaction between a fluid passing through and the substrate. Substrate may be a monolithic machined element or a collection of discrete bodies. The chamber conduits are connected to at least two metering devices, one controlling fuel and one air flow, whereby the substrate is exposed to measured quantities of fuel compositions and air. Heating devices are in thermal communication with the substrate and the source of air provided to the chamber, thus providing a method of controlling the temperature of the substrate and air flowing through the chamber. The propensity of a fuel composition to form deposits in an engine is determined by alternatively dispersing fuel composition and hot air upon the heated substrate then determining the mass of the deposits left on the substrate.

摘要： A viscometer for sensing or characterizing the stress required to shear a fluid at a given rate includes a pair of members coaxially mounted for relative rotation. Between the members is an annular gap defining a flow path for the fluid. The flow path is configured such that during differential rotation of the members, fluid is caused to flow through the annular gap that is a function of the differential rotation and the viscosity of the fluid. A sensor measures the torque or torque equivalent required to achieve such differential rotation between the members.

摘要： An apparatus for determining the viscosity of a fluid in a container (such as a pipe). The apparatus comprises a mechanism for transmitting a signal into a fluid in a container. The transmitting mechanism contacts the container and provides the signal to the fluid in the container. The apparatus comprises a mechanism for receiving the signal after the signal has passed through the fluid. The receiving mechanism contacts the container and receives the signal from the fluid in the container. The apparatus comprises a mechanism for determining the fluid in the container from the signal after the signal has passed through the fluid and determining the fluid viscosity from the amplitude and sound velocity. The determining mechanism is connected to the receiving mechanism. The method comprises the steps of transmitting a signal into fluid. Then there is the step of receiving the signal after it has passed through the fluid. Next there is the step of determining the attenuation of the signal as the signal has passed through the fluid. Then there is the step of finding the viscosity of the fluid in the container from the attenuation of the signal and transit time.
