Toward a new horizon for in-flight icing and wind engineering computational simulation

我们计划开发计算流体动力学（CFD）方法来解决，在一个有凝聚力的和国家的最先进的方式，一些长期悬而未决的问题，在飞行中结冰，只有经验规则已被应用。这些方法中的一些可以被证明对风力涡轮机领域和计算风工程也很重要，长期以来基于风洞测试。因此，所提出的研究在工程应用方面是广泛的，但在其基础数学和计算方法上紧密相连。 各种项目是开发先进的数值模型，以分析预测或计算： CFD-飞行中结冰：冰表面粗糙度表征 CFD-飞行中结冰：过冷大液滴和冰晶对飞机和喷气发动机的影响 CFD-飞行中结冰：冰破裂、脱落和后续跟踪 CFD-飞行中结冰：用于时间精确模拟的3D网格变形 CFD-飞行中结冰和CFD-风：湍流模型的多尺度方法 CFD-飞行结冰和CFD-风：降阶模型，大大减少求解时间 短期目标是开发，验证和验证拟议模型的数学和数值;而长期目标是积极继续我们作为先驱和领导者的成功追求，在全球范围内为计算模拟在合规（风）和认证（结冰）过程中发挥主导作用。 这项发现补助金代表了培养高素质人才的肥沃土壤，具有应用数学和工程应用经验的明智组合，他们将继续在加拿大具有战略重要性的领域发挥重要的学术和工业作用。

We plan to develop Computational Fluid Dynamics (CFD) methods to address, in a cohesive and state-of-the-art manner, some long pending issues of in-flight icing to which only empirical rules had been applied. Some of these approaches can be shown to also be of importance to the fields of wind turbines and for computational wind engineering, long based on wind tunnel testing. As such, the proposed research is broad in its engineering applications perspective, but tightly interconnected in its underlying mathematics and computational methodology. The various projects are to develop advanced numerical models to analytically predict or calculate: CFD-In-flight Icing: Ice surface roughness characterization CFD-In-flight Icing: Supercooled Large Droplets and Ice Crystals effects on aircraft and in jet engines CFD-In-flight Icing: Ice cracking, its shedding and subsequent tracking CFD-In-flight Icing: 3D mesh deformation for time-accurate simulations CFD-In-flight Icing and CFD-Wind: Multiscale approaches for turbulence models CFD-In-flight Icing and CFD-Wind: Reduced Order Models to considerably reduce solution times The short-term objective is to develop, verify and validate the mathematics and numerics of the proposed models; while the long-term objective is to vigorously continue our successful quest, as pioneers and leaders, in carving a predominant role for computational simulation in compliance (wind) and certification (icing) processes, worldwide. This Discovery grant represents a fertile ground to cultivate Highly Qualified Personnel, with a judicious mix of applied mathematics and engineering applications experience, who will continue playing important academic and industrial roles in areas of strategic importance to Canada.
