湍流基础研究进展及其对应用研究的推动
Advances in fundamental turbulence research and its promotion of applied research
摘要
Abstract
In the context of global climate change and the increasing frequency of extreme hydrological events,energy transformation and ecological governance impose higher demands on reducing energy consumption,improving system efficiency,and fostering new quality productive forces.Focusing on the core objectives of"scientific innovation"and"energy consumption reduction",this study proceeded from fundamental turbulence theory and systematically elucidated the guiding role of fundamental research breakthroughs in applied research and engineering technology development.By introducing a turbulence framework grounded in the physics of eddy motions,the limitations of the classical mixing length theory were overcome,and new analytical formulations for velocity distribution,turbulence intensity,sediment concentration distribution,and flow resistance were derived,overcoming the theoretical deficiencies of the classical logarithmic velocity profile and the Rouse equation in the near-wall region and near the free surface.The proposed sediment-carrying capacity formula is applicable not only to ordinary sediment-laden flows but also to high-sediment-concentration flows.These results enrich the theoretical foundations of hydraulics and river dynamics,promote theoretical advances in key river research issues such as water-sediment transport in the Yellow River,mobile-bed resistance,and model similarity laws,strengthen the academic support for the analysis of the prototype Yellow River,and provide strong support for the construction of the"Three Yellow Rivers".Moreover,the proposed framework demonstrates significant interdisciplinary application potential in areas including industrial pipeline transport,aeolian sand control,atmospheric and ecological process modeling,and energy-efficiency optimization of aero-engines.The findings indicate that advances in fundamental turbulence research can effectively support system-level energy-efficiency improvements,providing important scientific evidence for the coordinated advancement of energy transition,watershed ecological governance,and climate change adaptation.关键词
