✦ Synopsis

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 instrument the maximum temperature rise is about 3°C. Hence viscous heating effects can lead to observable errors when a coneand-plate instrument is operating at high speeds; such effects have been observed experimentally.

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
