Abstract
Способ измерения вязкости, включающий прокачку испытуемой среды через канал круглой формы поперечного сечения и определение параметров движения среды, а именно касательного напряжения и сдвиговой скорости деформации на поверхности канала, по которым определяют вязкость среды, отличающийся тем, что канал имеет замкнутую форму тора, а прокачка испытуемой среды происходит под действием изменяющихся во времени сил инерции и трения среды, возникших в результате резкой остановки вращающегося вокруг своей оси тора.A method for measuring viscosity, including pumping the test medium through a circular cross-section channel and determining the parameters of the medium’s motion, namely, the shear stress and shear strain rate on the channel surface, which determine the viscosity of the medium, characterized in that the channel has a closed torus shape, and pumping of the test medium occurs under the action of time-varying forces of inertia and friction of the medium resulting from a sharp stop of a torus rotating around its axis.
