Abstract

The invention relates to a gas-liquid two-phase bubbly liquid viscosity measuring method. The method comprises the following steps: 1, selecting syrup, injecting dry ice particles into the syrup, uniformly stirring, and sublimating the dry ice particles in the syrup to prepare a uniform and stable bubbly flow syrup; and 2, adding the prepared bubbly flow syrup to a transparent solution container, and measuring the viscosity of the syrup by adopting a liquid phase viscosity measuring apparatus. The liquid phase viscosity measuring apparatus comprises a workbench, a rheometer, a laser emitter, a high speed camera and a computer, the solution container is arranged below the rheometer, and the laser emitter and the high speed camera are connected with the computer through a transmission line. The measuring method and the measuring apparatus are simple and are easy to enforce, and can realize the accurate measurement of the transient and average viscosity of the gas-liquid two-phase bubbly flow. The method can be used for measuring and analyzing the rule of the influences of different physical parameter degrees of bubbles on the liquid phase viscosity.

Description

technical field [0001] The invention relates to a gas-liquid two-phase foam liquid viscosity measurement method and a liquid phase viscosity measurement device. Background technique [0002] To improve the mass and heat transfer properties in a single-liquid environment, bubbles of different diameters are often used as additives to inject into the liquid phase to achieve this purpose. The injection of bubbles not only improves the mass transfer and heat transfer characteristics of the single liquid phase, but also has a great impact on the rheological properties of the liquid phase itself. Therefore, an accurate understanding of the effect of bubble injection on the rheological properties of the liquid phase is very necessary for understanding and predicting the impact of bubble injection on the physical properties of the liquid phase. [0003] Although a variety of viscometers and rheometers have been developed at home and abroad, none of them can be directly used to measu...
