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.

加拿大森林不断需要保护免受害虫侵害，提供这一保护的关键方法之一是通过空中喷洒计划。 为了减轻环境副作用，已经开发了绿色生物农药（正在开发新的变体），并使用喷雾系统从飞机的空中递送。 由于这些新的生物农药成本高，重要的是产品达到其森林目标，而对附近的非目标区域的损失很少。 本研究的目的是应用先进的高性能计算为基础的仿真工具，从飞机上的生物农药液滴释放，直到其最终目的地在地面上的问题。 模拟依赖于超级计算机和基于空气动力学的数学模型，其提供比用于帮助靶向生物农药的当前（基于20世纪70年代）模型更高的分辨率。 据设想，在这项研究中应用的新的模拟方法将取代目前的目标定位方法的组成部分。 针对生物农药的能力的提高将鼓励在森林保护环境中全面采用此类产品。 这项拟议的研究将在五年内吸引四名研究生。 研究活动将提供培训，涉及计算机科学、机械和环境工程（包括大气建模）概念的融合。 一旦完成他们的工作，这些高素质的专业人员将能够为加拿大日益增长的需求做出贡献，为复杂的跨学科问题找到环境友好的解决方案。
