Turbulence theory and applications: an adaptive wavelet approach

点击翻译按钮获取中文摘要

Our world is mostly moving fluid. Seventy percent of the earth's surface is covered in water, and we live at the bottom of an atmosphere 1 000 km thick. Life itself depends on blood circulation in our arteries and veins. Our technology and well-being depends on machines that manipulate or move through fluids. We rely on efficient weather and climate prediction. These fluids are usually turbulent: seemingly chaotic, but also containing large coherent vortices. Examples include storms, flow over aircraft wings, wind blowing around large buildings, and blood flow through the heart. Although turbulent flows are ubiquitous in nature and technology, they are poorly understood: there is still no theory of turbulence. We do not even know how to accurately calculate strongly turbulent flows on a computer.
