摘要: The effects of reference environment on exergy losses a turbojet are examined, considering variable and two constant environments. percentage the total loss due to exhaust emission increases from 65% at sea level 70% 15,000 m, while composition this remains nearly with altitude. Exergy strongly dependent environment. magnitude varies by up 18% actual value when using reference-environment model. breakdown for 28%.
