METHOD OF DETERMINING THE VALUES OF FLOW PARAMETERS PROVIDING THE MAXIMUM ORIENTATION OF THE DRAWN AND PLASTIC NANOBOJECTS ALONG THE FLOW OF THE LIQUID ENVIRONMENT Russian patent published in 2018 - IPC G01N29/32 

FIELD: measurement technology.

SUBSTANCE: using to determine the values of the flow of parameters that provide the maximum orientation of elongated and laminar nanoobjects along the flow of the liquid medium. Summary of the invention is using of a measuring cell in the form of an annular channel of variable cross-section to create an accelerated flow, containing a streamline flow stimulator and an acoustic meter installed in the region of narrowing of the annular channel, with the help of which acoustic spectra of ultrasonic attenuation are measured in a sample of a liquid medium, under the measured spectra the longitudinal viscosity of a liquid medium is measured and the dependence of the longitudinal viscosity on the flow velocity of the liquid medium is determined, and according to the degree of narrowing of the flow cross-section in the measurement region and the measured dependence the critical value of the flow rate is calculated and the critical value of the degree of narrowing of the flow cross section above which the state of maximum orientation of elongated and laminar nanoobjects along the flow of the liquid medium is realized.

EFFECT: providing the possibility of determining the values of the flow parameters ensuring the maximum orientation of elongated and laminar nanoobjects along the flow in dispersions.
