摘要: Abstract The dynamic viscosities of biodiesel derived from ethyl esters fish oil, no. 2 diesel fuel, and their blends were measured 298 K down to respective pour points. Blends B80 (80 vol.% biodiesel–20 vol.% diesel), B60, B40 B20 investigated. All the viscosity measurements made with a Bohlin VOR Rheometer. Cloud point according ASTM standards. Arrhenius equations used predict pure Biodiesel (B100), fuel (B0) (B80, B40, B20) as function temperature. predicted agreed well values. An empirical equation for calculating these both temperature blend has been developed. Furthermore, based on kinematic density B100 up 573 K by Tate et al. [Tate RE, Watts KC, Allen CAW, Wilkie KI. three fuels at temperatures 300 °C. Fuel 2006;85:1010–5; densties 2006;85:1004–9] an predicting 277 K is given. Empirical cloud given give values in good agreement experiments. its increases decreases show Newtonian behaviour point. Dynamic viscosity, increase concentration blend.
