This work proposed a method to predict the dynamic viscosity values of the hypothetical acidic oils-based biodiesel fuels. A topological index that can formulate the molecular structural information of fatty acid methyl ester (FAME) components into dimensionless form was built from the...

A pure component topological index was integrated with the modified Grunberg–Nissan or the modified Dalton-type mass‑average equation to calculate the mean topological index χm,1 or χm,2 of five biodiesel fuels (peanut, canola, coconut, and palm, soybean oil). Then, the χm,1 or χm,2 was...
