Description
  • The goal of this study was the determination of basic physical properties such as density, calorifi c value and rheological properties of liquid biofuels. Biofuels on the base of bioethanol and rapeseed methyl ester were chosen. Following control samples were selected: diesel oil without admixture of methyl esters and commercially available diesel oils with small amount of methyl ester admixture (6.2 and 6.5%). Dynamic viscosities of individual samples were measured in the range from --10°C to 50°C. Th en dependence of shear rate on shear stress was measured at temperatures --10, 0, 20 and 40°C. Th e most of samples showed the Newtonian behaviour. However, samples with high content of methyl esters or pure methyl esters showed thixotropy behaviour at the low temperature.
