Critical properties of mixtures of ethanol and primary reference fuels
Ethanol gasoline is one of the important new clean fuels,and its critical properties are the basic data for studying its supercritical or transcritical injection combustion.The critical properties of the ternary mixtures of ethanol and primary reference fuels(iso-octane and n-heptane)were measured by a low residence time flow method for the first time.The results show that the critical temperature(Tc)first decreases and then increases with the increase of mole fraction of ethanol,while critical pressure(pc)increases continuously.Based on the Redlich-Kister equation,a model is presented for the critical properties of ternary mixtures of ethanol+iso-octane+n-heptane.The maximum average absolute relative deviations of Tc and pc are 0.08％and 0.40％,respectively.
