Viscosity correlation for non-newtonian waxy oils

الملخص EN

Rheological characteristics of six types of waxy oils were mea¬sured with rotational co-axial cylinder viscometer at different temperatures of 282, 285, 288, 291, 294 and 297K.

A modified form of Eyring equation relating viscosity, temperature, and shear rate is proposed as ᵤ= A eB/T yc The correlation was developed using superposition approach.

Experimental data show that rheological behavior of waxy oil change from a Newtonian fluid into non-Newtonian fluid at lower temperatures and at higher wax content.

The modified correlation has been found to fit the experimental data adequately.
