CCP Turbulence

我们的日常生活被液体的流动所包围--甚至是维持的--。血液通过我们体内的血管流动，空气进入我们的肺部。流体流动分散了城市和室内环境中的颗粒物空气污染。流体流动对我们的运输和我们的工业起着至关重要的作用。我们的车辆在空气和水中行驶，这些液体由混合在发动机燃烧室中的其他液体提供动力。如果不能更好地了解流体的动力学，我们今天面临的许多与环境和能源有关的问题都不可能得到解决。从实践的角度来看，与科学家和工程师相关的流体流动是湍流；湍流是规则，而不是例外。到目前为止，由于描述流体运动的完整方程的复杂性，关于流体流动现象的完整理论仍然缺乏。然而，在许多领域，从工程应用(例如工业过程、推进和发电、汽车和飞机设计)到环境科学和技术(例如空气质量、天气预报、气候预测、洪水灾害监测)，它们的理解和控制对于改进技术，特别是在对生态影响最小的情况下以及对事件的预测至关重要。最近，高性能计算的应用取得了重大进展，计算流体力学现在是对实验和理论的重要补充。CCP湍流的目标是(I)显著增强英国模拟复杂湍流问题的能力，这些问题直到最近还超出想象，(Ii)提供用户支持、培训和联网活动，以及(Iii)在新兴硬件平台上实现能力计算。软件开发和合作活动将为英国研究人员提供一个独特的机会，率先探索新的物理，并回答有关在一系列工程、生理和地球物理应用中发现的湍流的物理和建模的基本问题。

Our daily life is surrounded - and even is sustained - by the flow of fluids. Blood moves through the vessels in our bodies, and air flows into our lungs. Fluid flows disperse particulate air pollution in the turbulent urban as well as indoor environments. Fluid flows play a crucial role for our transportation and our industries. Our vehicles move through air and water powered by other fluids that mix in the combustion chambers of engines. Many of the environmental and energy-related issues we face today cannot possibly be tackled without a better understanding of the dynamics of fluids. From a practical point of view, fluid flows relevant to scientists and engineers are turbulent ones; turbulence is the rule, not the exception. To date, a complete theory of fluid flow phenomena is still missing because of the complexity of the full equations describing the motion of a fluid. Their understanding and control is however crucial to improve technologies especially with minimal ecological impact as well as to anticipate events, in many areas ranging from engineering applications (e.g., industrial process, propulsion and power generation, car and aircraft design) to environmental sciences and technologies (e.g., air quality, weather forecasting, climate predictions, flood disasters monitoring).Significant progress has been made recently using high performance computing, and computational fluid dynamics is now a critical complement to experiments and theories. The CCP Turbulence is aiming to (i) considerably enhance the UK capabilities to simulate complex turbulence problems that were until very recently beyond imagination, (ii) offer user support, training and networking activities and (iii) enable capability computing on emerging hardware platforms. The software developments and collaborative activities will give UK researchers a unique opportunity to be the first to explore new physics and to answer basic questions regarding the physics and modelling of turbulent flows found across a range of engineering, physiological and geophysical applications.
