Název v původním jazyce

Temperature dependence density and kinematic viscosity of petrol, bioethanol and their blends

Popis výsledku v původním jazyce

This paper deals with the flow behaviour conventional petrol, bioethanol and their blends, especially E15 and E85. The temperature dependence density and kinematic viscosity of samples have been measured and modelled. The rotary rheometer has been used to the measuring temperature dependence kinematic viscosity of fuel and blends. The digital densitometer with the fuel scale has been used to the measuring temperature dependence density of fuel and blends. The range of temperature measurement has been stated from the --10 to 40°C. The mathematic models (polynomial and exponential function) have been created according to the general formulae. The coefficients of determination R2 have achieved high values 0.99 for temperature dependence density and from 0.89 to 0.97 for temperature dependence kinematic viscosity. The created mathematical models could be used to the predict flow behaviour of petrol, bioethanol and their blends.
