Abstract
The Arrhenius correlation, the Vogel–Fulcher–Tamman correlation and a four-parameter correlation for the temperature dependent viscosity are compared and checked for saturated liquids by using the viscosity data in the NIST database. 52 substances including hydrocarbons, refrigerants, and some others are considered. By comparing the calculated numerical results from the three correlations with the data from the NIST database, it is found that the four-parameter correlation can predict the NIST data with average absolute deviation (AAD) less than 5% for all the 52 liquids, AAD less than 1% for 39 liquids. Better accuracy of the four-parameter correlation compared to the Arrhenius correlation and the Vogel–Fulcher–Tamman correlation is found.
