Abstract:
The results of the modeling of hydrodynamic processes in the operating space of $3$ different types of fixed flow capillary viscometers are represented in the article. The results were obtained from computational solution of the Navier–Stokes equation for laminar flow with the use of finite-element method. The influence of capillary tube and cylinder bottom shape on the metrological performance of viscometer was established.
Keywords:liquid flow modeling, hydrodynamic features of capillary method, capillary viscometer, measurement of viscosity.
