  aircraft plume
Taking chemical conversion in the aircraft plume into account in the CTM explicitly, by means of modified aircraft NOx emissions, a significant reduction of the aircraft-induced NOx and ozone perturbations is realised.
      
This study and preliminary report provide new insights into aircraft plume behavior, and data for more accurate modeling of plume rise and spread.
      


After the weakness of Hottel's method for solving plume radiation is discussed, an integral differential equation and its numerical solution form of plume radiation transmission in a dissipative and emitting medium are derived. Transportation equations of solid angle in radiation geometry are also derived. Finally, a computative example of integrate infrared radiation in a typical direction and of spectral distribution of a jet aircraft plume with chemical reaction is given.

讨论了 Hottel法用于喷气流辐射计算的弱点 ,推演了辐射在耗散和发射性介质中传输的积微分方程 ,并在散射量较小时得出了宜于数值解的高温喷气流辐射传输方程。还推演了观测坐标系与流场坐标系不一致时辐射立体角的转换关系。最后给出了计及化学反应的喷气流算例在空间典型点处的积分辐射量及光谱分布 ,并将其和实测数据进行了比较
