This project will investigate the lifespan of large-scale repeating patterns within turbulent boundary layers (the thin layer of chaotic fluid that envelopes a body as it moves through a fluid). These recurrent patterns play an important role in our lives, dictating the drag of aircraft and dominating environmental processes in the lower atmosphere.

该项目将研究湍流边界层（当物体在流体中移动时包围物体的混沌流体薄层）内大规模重复模式的寿命。这些反复出现的模式在我们的生活中发挥着重要作用，决定了飞机的阻力并主导了低层大气的环境过程。
