尾涡作为限制飞机间隔的重要因素，如何加速尾涡耗散以提升机场容量一直是国内外学者研究重点。基于真实地形开展数值模拟仿真实验，就地形对于尾涡演化影响效果进行了研究。选用F构型A332机翼模型在重庆江北机场02R跑道着陆为拟研究场景，利用Fluent软件基于SST k-ω湍流模型进行数值模拟实验，将实验所得计算结果与无地形条件下的计算结果进行对比分析。结果表明：地形能够引导尾涡移动，从而增加下沉距离使其远离下滑道，根据分析结果显示，有地形条件下增加最大下沉距离为无地形条件下的22倍，同时地形对尾涡的形态破坏能够更早激发Crow长波不稳定性，使其在9个翼展位置基本完成内机身襟翼涡的耗散，且地形可限制尾涡影响范围，有地形条件下涡核间距最大缩减量约为26.5%。因此，所研究的真实地形对于减小后机尾涡遭遇风险，缩小尾流间隔，提升跑道容量具有积极作用。

The acceleration of wake vortex dissipation, a critical aspect in aircraft spacing, has consistently been a focal point of research for scholars both domestically and internationally to enhance airport capacity. A numerical simulation experiment was conducted based on real terrain to study the effect of terrain on the evolution of wake vortices. The F-configuration A332 wing model was selected as the proposed research scenario for landing on runway 02R at Chongqing Jiangbei Airport. Fluent software was used to conduct numerical simulation experiments based on the SST k-ω turbulence model, and the calculated results were compared and analyzed with those under no terrain conditions. The investigation indicates that the maximum sinking distance in terrain situations is 22 times greater than that in non-terrain conditions. The terrain's alteration of the wake vortex's structure can expedite the Crow long-wave instability, enabling the dissipation of the inboard flap fuselage vortex to occur at around 9 wingspan locations. The topography can restrict the extent of the wake vortex's influence. The highest decrease in vortex core spacing under terrain conditions is around 26.5%. Consequently, the actual terrain analyzed positively influences the mitigation of wake vortex encounters for subsequent aircraft, decreases wake vortex separation, and enhances runway capacity.
