摘要: Abstract The present paper deals with experimental and theoretical investigation of surface tension, apparent viscosity viscoelastic properties sal oil methyl ester biodiesel its blends petrodiesel at different temperature. Several methods were used to predict tension biodiesel–petrodiesel blends. Satri–Rao method based on the corresponding state predicts very well, whereas UNIFAC–VISCO group contribution accurately. To biodiesel, six unknown interaction parameters determined proposed then viscosities recommendation was given which proportion normal diesel be mixed get proper European standard grade fuel. Viscoelastic (i.e., structural stability, storage modulus, loss complex tangent) as a function amplitude, frequency temperature using parallel plates rotational viscometer in linear range. Finally, generalized Cox–Merz establish relation between
