摘要: Abstract A fuel, here ethanol or decane, and nitrogen are fed at elevated pressure temperature through a micro capillary of fused silica. The flow inside the is characterized by alternating liquid- vapor-phase segments that accommodate to thermodynamic equilibrium set pressure. composition equilibrated liquid vapor measured in situ remotely Raman spectroscopy. Temperature-composition (Tx) vapor-liquid equilibria were for pressures between 3 MPa 8 MPa up highest mixture critical 593 K this range. Comparison scarce literature data these conditions GERG-2008 model, resembling IC-engines time injection, shown.
