According to the World Nuclear Association: "Fusion power offers the prospect of an almost inexhaustible**source of energy for future generations, but it also presents so far insurmountable engineering challenges".**General Fusion, based in Burnaby, BC, is one of three international companies that are actively working to**create a commercially viable nuclear fusion reactor. The General Fusion design uses magnetized target fusion,**in which plasma is injected into a rotating liquid before being compressed by the liquid. Novel scientific and**engineering challenges are constantly arising as the design of the full-scale reactor and it's lab-scale equivalent,**are modified, with the latest design having the liquid injected through a rotating honeycomb screen/grid. One**of the major engineering challenges facing General Fusion is the ability to scale up the results from the**laboratory based measurements to the full-scale reactor, as there is no prior work on this specific topic. This**NSERC Engage Grant will leverage McGill's expertise in grid turbulence and non-intrusive optical**measurement techniques to elucidate key scaling parameters and gain insight into the complex turbulent flow**that is being developed as the liquid is ejected through honeycomb screen/grid structure. The knowledge and**expertise gained through this Engage Grant will directly influence the design of the fusion reactor and ensure**that Canada remains a world leader in nuclear fusion technology and would provide the Canadian people with a**source of clear energy at affordable prices.

根据世界核协会的说法：“聚变发电为后代提供了几乎取之不尽的能源的前景，但它也提出了迄今为止无法克服的工程挑战”。总部位于卑诗省伯纳比的通用聚变公司是三家积极致力于创造商业上可行的核聚变反应堆的国际公司之一。通用聚变设计使用磁化靶聚变，** 其中等离子体在被液体压缩之前被注入旋转的液体中。新的科学和工程挑战不断出现，因为全尺寸反应器的设计和它的实验室规模的等效物 ** 被修改，最新的设计使液体通过旋转的蜂窝筛/网格注入。General Fusion面临的主要工程挑战之一是将基于实验室的测量结果扩展到全尺寸反应堆的能力，因为之前没有关于这个特定主题的工作。这项 **NSERC Engage Grant将利用麦吉尔在网格湍流和非侵入式光学 ** 测量技术方面的专业知识，阐明关键的缩放参数，并深入了解液体通过蜂窝筛/网格结构喷射时正在开发的复杂湍流 **。通过这项参与赠款获得的知识和专业知识将直接影响聚变反应堆的设计，并确保加拿大在核聚变技术方面保持世界领先地位，并将以负担得起的价格为加拿大人民提供清洁能源。
