The temperature rise resulting from viscous dissipation in the fluid in a cone-and-plate viscometer is derived approximately using a variational method. In the derivation it is not necessary to make reference to any specific rheological model. It is concluded that for one commercially available inst

Analytical solutions are given for the velocity and temperature profiles in non-Newtonian fluids between two infinite parallel planes, one of which is moving fast enough that viscous dissipation heating effects are important. The temperature-and shear-dependence of the non-Newtonian viscosity is tak
The usefulness of the cone-and-plate viscometer is limited to rotational speeds low enough for the assumption of primary flow to be valid. Experimental data for Newtonian liquids show that a theoretical result of Walters and Waters[5] satisfactorily predicts the conditions at which the effect of sec
It was shown using a cone-plate rotational viscometer that the apparent viscosity of a dilute aqueous solution of sodium hyaluronate decreased gradually during the measurement. Hyaluronic acid (HA) forms a characteristic network by entanglements coupling, so two hypotheses could be postulated from t
