“…In order to shed light on the reasons for such shapes one can apply one of the numerous models available for calculating the dynamic viscosity. Reviews of possible approaches are given in [13,14]. From the models presented in [14] the Kozlov-equation [15] is selected for the present study.…”

“…The oscillation parameters, the sample's density and mass as well as the momentum of inertia and the crucible's inner radius are necessary quantities to calculate the dynamic viscosity following Roscoe's equation (5) and (6). As mentioned previously, the calculation is necessarily performed in a numerical way, i.e.…”

“…where: The description of non-Newtonian fluids in the form of equations (7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26) has the advantage of determining their apparent viscosity, which significantly simplifies algorithmic procedures in numerical programming. This mathematical notation has also disadvantages such as the necessity to determine limiting apparent viscosities, which is not always technically and technologically feasible [8].…”

The objective of this article is to review models for calculating the value of liquid dynamic viscosity. Issues of viscosity and rheological properties of liquid ferrous solutions are important from the perspective of modelling, along with the control of actual production processes related to the manufacturing of metals, including iron and steel. Conducted analysis within literature indicates that there are many theoretical considerations concerning the effect of viscosity of liquid metals solutions. The vast majority of models constitute a group of theoretical or semi-empirical equations, where thermodynamic parameters of solutions, or some parameters determined by experimental methods, are used for calculations of the dynamic viscosity coefficient.This article presents equations belonging to four groups of models for calculating the value of the dynamic viscosity coefficient: rheological models, non-rheological models, non-rheological and rheological models for calculating viscosity of metals. The last group of equations is developed by own experiments -high temperature rheological liquid steel measurements.Keywords: viscosity models, rheology, viscosity, viscosity of metals Celem prezentowanego artykułu jest dokonanie przeglądu modeli służących do obliczania wartości współczynnika lepkości dynamicznej cieczy. Zagadnienia lepkości oraz właściwości reologicznych ciekłych roztworów żelaza są ważne z punktu widzenia modelowania, a także sterowania rzeczywistymi procesami technologicznymi w odniesieniu do wytwarzania metali, w tym surówki i stali. Z przeprowadzonej analizy literaturowej wynika, że istnieje wiele teoretycznych rozważań nad zjawiskiem lepkości ciekłych roztworów metali. Zdecydowana większość modeli stanowi grupę równań teoretycznych, bądź półempirycz-nych, w których do obliczania wartości współczynnika lepkości dynamicznej wykorzystywane są wielkości termodynamiczne roztworów lub pewne wielkości wyznaczane metodami eksperymentalnymi.W artykule zaprezentowano równania należące do czterech grup modeli służących do obliczania wartości współczynnika lepkości dynamicznej: modele reologiczne, modele niereologiczne oraz modele niereologiczne oraz reologiczne wykorzystywane do obliczania lepkości metali. Ostatnia grupa równań została opracowana w ramach badań własnych -wysokotemperaturowych pomiarów reologicznych ciekłej stali.
