Numerical simulation of transitional boundary-layer flows

流体流动的行为，因为它经历了层流状态和湍流状态之间的过渡是一个迷人的研究领域的基本重要性，在流体动力学。对于固体表面（如飞机机翼）上的所谓边界层流动，更好地理解这一过程是如何发生的，将有利于各种工程应用。边界层流动中层流-湍流转捩的研究通常涉及三种互补的方法：（i）控制流体流动行为的方程的数学分析;（ii）物理实验和（iii）数值模拟。这项工作的目的是汇集两个活跃的研究人员谁都有显着的专业知识（iii）。寻求资金，使他们将有机会在访问对方在他们的家乡机构，在卡迪夫和亚利桑那州，讨论一些共同感兴趣的问题，并探讨一些可能性，为未来的合作研究。

The behaviour of a fluid flow as it undergoes the transition between a laminar state and a turbulent state is a fascinating area of research of fundamental importance in fluid dynamics. An improved understanding of how this process occurs for cases of so-called boundary-layer flow over solid surfaces, such as aircraft wings, would be of benefit in a wide variety of engineering applications. The study of laminar-turbulent transition in boundary-layer flows typically involves three complementary approaches: (i) mathematical analysis of the equations that govern the behaviour of the fluid flow; (ii) physical experiments and (iii) numerical simulations. The work that is proposed is aimed at bringing together two active researchers who both have significant expertise in (iii). Funding is sought so that they will have the opportunity at visit each other at their home institutions, in Cardiff and Arizona, to discuss a number of problems of common interest and to explore some possibilities for future collaborative research.
