“…This work [4] is the first to apply two methods in parallel: planar laser-induced fluorescence (PLIF) and particle image velocity (PIV) to measure the viscosity of moving fluid in a reservoir. In the aerohydrodynamic method [5], the authors propose to apply a pulsating air jet to the liquid surface and measure the viscosity by analyzing the parameters of the waves generated on the surface. Litvinenko et al [6] suggests using observation of the parameters of the gas inclusion and its motion to measure viscosity.…”

The transportation modes depend entirely on the viscosity of the oil. To date, none of the viscometric methods are able to provide measurements to meet all the requirements of oil flow, features of main oil pipelines, and trends in the oil industry, such as decarbonization and digitalization. The method of inline viscosity measurement of multiphase flow through a metal pipeline can be based on direct gamma ray measurement. It is stipulated by the ability of gamma-radiation to penetrate through the pipeline material without destroying it, as well as by the ability to work with flows containing free gas and the high capability to be introduced into automatic control systems. The authors consider the physical forces acting on the gas inclusions in the oil flow. They determine the physical dependence between the parameters determined by the radioisotope method and the viscosity of oil in the three-phase flow. These studies show good agreement with the work of other scientists. The prospect of further research will be to clarify the mathematical model of gas-oil flow, to increase the accuracy by reducing the number of assumptions made.

On a daily basis, we stir tea or coffee with a spoon and leave it to rest. We know empirically the larger the stickiness, viscosity, of the fluid, the more rapidly its velocity slows down. It is surprising, therefore, that the variation, the decay rate of the velocity, has not been utilized for measuring (kinematic) viscosity of fluids. This study shows that a spectroscopy decomposing a velocity field into fluid modes (Stokes eigenmodes) allows us to accurately measure the kinematic viscosity. The method, fluid mode spectroscopy (FMS), is based on the fact that each Stokes eigenmode has its inherent decay rate of eigenvalue, and the dimensionless rate of the slowest decaying mode is constant, dependent only on the normalized shape of a fluid container, obtained analytically for some shapes including cylindrical containers. The FMS supplements major conventional measuring methods with each other, which is particularly useful for measuring relatively low kinematic viscosity and for a direct measurement of viscosity at zero shear rate without extrapolation. The method is validated by the experiments of water poured into an open cylindrical container, as well as by the corresponding numerical simulations.
