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

加拿大的森林经常需要防止虫害的保护，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，已经开发了绿色生物杀虫剂(正在开发新的变种)，并使用喷雾系统从空中运送。由于这些新的生物杀虫剂的成本很高，重要的是该产品在达到其森林目标的同时对附近的非目标区域几乎没有损失。本研究的目的是将先进的高性能计算模拟工具应用于生物农药液滴从飞机上释放到其最终目的地地面的问题。这些模拟依赖于超级计算机和基于空气动力学的数学模型，这些模型提供的分辨率比目前(20世纪70年代基于S的)模型用于辅助靶向生物杀虫剂的模型更高。可以预见，本研究中应用的新的模拟方法将取代当前目标方法的组成部分。针对生物杀虫剂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.
