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.

流体在层流状态和湍流状态之间转换时的流动行为是流体动力学中具有重要基础意义的一个引人入胜的研究领域。对于固体表面（如飞机机翼）上所谓的边界层流动如何发生这一过程的更好理解，将有利于各种各样的工程应用。边界层流动中层流-湍流过渡的研究通常涉及三种互补的方法：(i)对控制流体流动行为的方程进行数学分析；（ii）物理实验和（iii）数值模拟。提议的工作旨在将两位在（iii）方面都具有重要专业知识的活跃研究人员聚集在一起。寻求资助，以便他们有机会在各自位于卡迪夫和亚利桑那州的家乡机构相互访问，讨论共同感兴趣的一些问题，并探索未来合作研究的一些可能性。
