RHEOLOGICAL PROPERTIES OF RAPESEED OIL AND HYDRAULIC OIL
Abstract
This article presents the rheological behavior of refined rapeseed oil and hydraulic oil. Apparent viscosity of both oils was determined at temperatures between 40 and 90°C and shear rates ranging from 3.3 to 120 s-1. The aim of the study was to find a polynomial dependence of oil viscosity on temperature and shear rate. The modified Andrade equation was used. Constants A, B, C and correlation coefficient were determined by correlating a characteristic polynomial equation of each curve.
