Viscosity correlation development for corn oil biodiesel-diesel fuel blends

Abstract

In this study, the lowest dynamic viscosity corn oil biodiesel was produced using methanol as alcohol and potassium hydroxide as catalyst by means of transesterification reaction. Dynamic viscosities of produced corn oil biodiesel and its blends with diesel fuel at different temperatures were measured according to international standard. Effects of temperature and biodiesel content in blend on changes of their dynamic viscosities were examined. Changes were described by means of regression models such as two-term exponential model and three-term logarithmic model. Constants and regression coefficients of these models were computed and reported in tables.
