Thermodynamic Analysis of Fuel Vapor Characteristics in an Aircraft Fuel Tank Ullage

Abstract

As a prerequisite to a comprehensive analysis of aircraft fuel tank fire and explosion hazards, a vapor-liquid equilibrium thermodynamic analysis was developed to assess the fuel vapor behavior in an aircraft fuel tank ullage. The analysis was based on the Peng-Robinson equation of state and the extended corresponding-states method. Jet-A fuel was treated as a pseudo single-component fluid. The calculated fuel/air mass ratios followed the trend observed in previous measurements.
