CCP Turbulence

我们的日常生活被流体的流动所包围，甚至是持续的。血液在我们体内的血管中流动，空气流入我们的肺部。流体流动分散湍流城市以及室内环境中的颗粒空气污染。流体流动对我们的运输和工业起着至关重要的作用。我们的车辆通过空气和水移动，由发动机燃烧室中混合的其他流体提供动力。如果不更好地了解流体动力学，我们今天面临的许多环境和能源相关问题就不可能得到解决。从实际的观点来看，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。迄今为止，由于描述流体运动的完整方程的复杂性，流体流动现象的完整理论仍然缺失。然而，对它们的理解和控制对于改进技术，特别是在最小生态影响的情况下，以及在从工程应用（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）。最近，使用高性能计算取得了重大进展，计算流体动力学现在是实验和理论的重要补充。CCP Turbulence旨在（i）大大提高英国模拟复杂湍流问题的能力，直到最近才超出想象，（ii）提供用户支持，培训和网络活动，（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，成为第一个探索新物理学的人，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.
