The Transitional and Turbulent Structure of Rotating Disk Boundary Layers

能源、材料加工、制造和空气动力学领域的设计优化通常取决于表面附近的流体流动（壁流），并且许多这样的流动是三维的（3-D）。 目前，三维壁流知之甚少，因此，我们的目标是提供第一个全面的研究原型3-D壁流旋转盘。在定制的设施中进行的实验将涵盖重要的流动状态（过渡和湍流），新型传感器将量化详细的三维流动结构。通过阐明临界不稳定性情景和揭示湍流标度结构，该项目将从根本上推进三维壁流的物理理解和分析计算模型

Design optimization in areas of energy, materials processing, manufacturing and aerodynamics often depends on fluid flows adjacent to surfaces (wall-flows), and many such flows are three-dimensional (3-D). At present, 3-D wall-flows are poorly understood, and thus we aim to provide the first comprehensive study of the prototypical 3-D wall-flow on a rotating disk. Experiments in a bespoke facility will cover the important flow regimes (transitional and turbulent), and novel sensors will quantify the detailed 3-D flow structure. By clarifying critical instability scenarios and revealing turbulent flow scaling structure, this project will fundamentally advance physical understanding and analytical and computational models of 3-D wall-flows
