Method for Determining the Mixing Ratio of Aviation Biofuel and Petroleum Based Aviation Fuel
Based on the difference of performance parameters between aviation biofuel and petroleum based aviation fuel,the mixing model of aviation biofuel and petroleum based aviation fuel was established by select density and kinematic viscosity.The density at 15℃and kinematic viscosity at 20℃of mixed fuels were tested,and the working curve of mixing ratio and performance parameters was obtained,and the relationship was fitted.Testing the density at 15℃and kinematic viscosity at 20℃of mixed fuels with known biofuel ratio,and the calculated ratio was obtained,which was compared with the known proportion.The results show that the fitting effect of the mixing model is good when mixing proportion is used as abscissa,density and viscosity as ordinate.When the model is used to simulate the density at 15℃and the kinematic viscosity at 20℃of mixed fuels changes with the proportion of biofuel in mixture separately,the calculated proportion and the actual proportion is similar in the range of 0%～100%,and the agreement is good.The model can be used to determine the method of mixing ratio of aviation biofuel in blended fuels,which can be used to guide the practical production and application of aviation blended fuels.
