Coefficients for the calculation of thermophysical properties of indolene/ethanol biofuels for transcritical engine simulations

摘要

Driven by fuel economy and emission control concerns, modern automotive internal combustion engines operate at increasingly higher pressures and temperatures. The development of new low emission advanced combustion concepts rely on accurate predictions of the fuel mixture formation and combustion, sometimes near or across the critical point of the fuel blend. The present work provides libraries of thermodynamic and transport properties of automotive certification fuel surrogate, indolene, and its mixtures with ethanol E5, E10, E15, E20, E25, E50 and E85, to be used in the subcritical and supercritical range, in order to make transcritical fuel predictions possible and accurate.
