  • Cone/Plate Rheometer and Capillary Viscometer

    Cone/Plate viscometer measures the torque required to rotate a cone in a fluid for the determination of the viscosity of fluid. ❑Can be used as a traditional viscometer for collection of single speed viscosity data through the easy to use keypad. ❑Can be used with Rheocalc software to perform all control and data collection

  • A Basic Introduction to Viscometry

    'Cone and Plate' viscometers use a cone of very shallow angle in theoretical contact with a flat plate. With this system the shear rate beneath the plate is constant to a modest degree of precision, a graph of shear stress (torque) against shear rate (angular velocity) yields the viscosity. Rotational viscometers fall into two main

  • Radial Flow in the ConePlate Viscometer Nature

    CONEPLATE viscometers are widely used today to measure the flow properties of both Newtonian and nonNewtonian materials. The basic idea which led to the coneplate geometry came from Mooney and Ewart1, who were trying to eliminate end corrections in coaxial cylinder viscometers. In deriving the equations

  • Exactsolution for coneplate viscometry: Journal of Applied Physics

    The viscosity of a Newtonian fluid is often measured by confining the fluid to the gap between a rotating cone that is perpendicular to a fixed disk. We call this experiment coneplate viscometry. When the cone angle approaches π/2 π / 2, the viscometer gap is called narrow. The shear stress in the fluid, throughout a narrow

    The rotating cup is preferred in some cases because it reduces the onset of Taylor vortices at very high shear rates, but the rotating bob is more commonly used as the instrument design can be more flexible for other geometries as well. 'Cone and plate' viscometers use a narrow angled cone in close proximity to a flat plate.

  • Modelling rheological coneplate test conditions CiteSeerX

    ABSTRACT. Control with flow conditions is of paramount importance in relation to rheological tests. Special focus is made on the shear rate distribution in the flow volume of cone/plate test geometries and on the shear stress dependence on the central gap. Small variations in the central gap due to temperature variations

  • Nonlinear Flow Affects Hydrodynamic Forces and Neutrophil

    We present a theoretical and experimental analysis of the effects of nonlinear flow in a cone–plate viscometer. The analysis predicts that flow in the viscometer is a function of two parameters, the Reynolds number and the cone angle. Nonlinear flow occurs at high shear rates and causes spatial variations in wall shear

    In order that there be only one nonzero component of the stress tensor for a nonNewtonian fluid in a coneplate viscometer, inertial forces must be neglected with respect to viscous forces in the equation of motion.
