Combined full-physics aircraft wake and atmospheric modelling of droplet deposition

加拿大的森林一直需要防止害虫，而提供这种保护的关键方法之一是通过空中喷洒计划。为了减轻对环境的副作用，绿色生物农药已经被开发出来（新的变体正在开发中），并使用喷雾系统从飞机上通过空气输送。由于这些新型生物农药的高成本，重要的是要使产品达到其森林目标，而不会对附近的非目标区域造成损失。目前的研究旨在应用先进的高性能计算模拟工具来解决生物农药液滴从飞机释放到最终目的地地面的问题。模拟依赖于超级计算机和基于空气动力学的数学模型，这些模型提供了比当前（基于20世纪70年代的）用于帮助定位生物农药的模型更高的分辨率。设想在本研究中应用的新的仿真方法将取代现有瞄准方法的组成部分。针对生物农药的能力的提高将鼓励在森林保护环境中充分采用这类产品。

Canadian forests are in constant need of protection from pests and one of the key methods for providing this is through aerial spray programs. In order to mitigate environmental side effects green biopesticides have been developed (with on-going development of new variants) and are delivered from the air from an aircraft using a spray system. Due to the high cost of these new biopesticides it is important that the product reach its forest target with little loss to nearby off-target zones. The present research is aimed at applying advanced high-performance computing based simulation tools to the problem of biopesticide droplet release from the aircraft until its final destination on the ground. The simulations rely on supercomputers and aerodynamics based mathematical models that provide greater resolution than the current (1970's based) models used to assist in targeting the biopesticides. It is envisioned that the new simulation approach applied in this research will replace components of the current targeting methods. The improved ability to target biopesticides will encourage the full adoption of such products in forest protection settings. The proposed research will engage four graduate students spread over a five year period. The research activities will provide training involving a blend of computer science, mechanical and environmental engineering (including atmospheric modelling) concepts. Once having completed their work, these highly qualified professionals will be capable of contributing to Canada's growing need to find environmentally friendly solutions to complex interdisciplinary problems.
