摘要

由于溶解氧参与燃料沉积物的形成，因此了解溶解氧浓度对燃料热稳定性的影响对燃料系统设计至关重要。本文研究了溶解氧可用性和添加剂对喷气燃料热稳定性的综合影响。在模拟复杂热流环境的三分式换热器中对JP-8喷气燃料进行了实验研究。研究了进气口溶解氧含量的变化，并在部分耗氧和完全耗氧两种条件下对沉积进行了研究。研究了热稳定性添加剂包的影响。在JP-8燃料中发现的一个有趣的结果是，由于氧气消耗减少，在加热区域形成的沉积物增加，但与添加剂包相反。

The Effects of Dissolved Oxygen Concentration, Fractional Oxygen Consumption, and Additives on JP-8 Thermal Stability

Since dissolved oxygen participates in fuel deposit formation, knowledge of the effects of dissolved oxygen concentration on fuel thermal stability is critical for fuel system design. In this work, the combined effects of dissolved oxygen availability and additives on jet fuel thermal stability are studied. Experiments with JP-8 jet fuel were conducted in a three-part heat exchanger which simulated a complex thermal and flow environment. The dissolved oxygen content at the flow inlet was varied, and deposition was studied under conditions of either fractional or complete oxygen consumption. The effects of a thermal stability additive package were also studied. An intriguing result found with JP-8 fuels is an increase in deposits formed in heated regions for decreased oxygen consumption, but inverse behavior with the additive package.
