THEORETICAL AND EXPERIMENTAL ANALYSIS OF FLUID FLOW VISCOMETERS IN LIQUIDS (OIL, WATER AND ETHANOL) REGION BASED IN FLUENT SOFTWARE

This paper describes the fluid flow simulation results in the working space of fixed flow capillary viscometers of different configurations that are obtained on the basis of numerical solution of the Navier-Stokes equations for laminar flow using the experimental method. The influence of the capillary tube length and shape of the cylinder at the bottom the metrological characteristics of the viscometer. Given received during mathematical experiment conducted, the results developed functional diagram of the device measuring the viscosity. The aim of this paper is to model a few script using Fluent. The purpose of doing so was to see how exact the program at modeling fluid flow viscometers in liquids in order to see if computational fluid dynamics has preceding enough to do away with the classical methods.
