Abstract EN
In transport phenomena, precise knowledge or estimation of fluids properties is necessary, for mass flow and heat transfer computations.
Viscosity is one of the important properties which are affected by pressure and temperature.
In the present work, based on statistical techniques for nonlinear regression analysis and correlation tests, we propose a novel equation modeling the relationship between the two parameters of viscosity Arrhenius-type equation, such as the energy ( E a ) and the preexponential factor ( A s ).
Then, we introduce a third parameter, the Arrhenius temperature ( T A ), to enrich the model and the discussion.
Empirical validations using 75 data sets of viscosity of pure solvents studied at different temperature ranges are provided from previous works in the literature and give excellent statistical correlations, thus allowing us to rewrite the Arrhenius equation using a single parameter instead of two.
In addition, the suggested model is very beneficial for engineering data since it would permit estimating the missing parameter value, if a well-established estimate of the other parameter is readily available.
