Abstract

Corrugated Plate Sidewall Steel Aqueduct (CPSSA) is a specialized hydraulic structure for water conveyance. This paper investigates the effects of fluid parameters and CPSSA design parameters on flow hydrodynamics via combined experiments and simulations. A water–structure efficiency index is introduced to optimize the design of CPSSA. A CPSSA model with a scale of 1:20 was designed and tested, and numerical simulations considering fluid–structure interactions were performed. The results indicate that the water velocity and corrugated plates significantly impact flow velocity distribution and boundary layer thickness. Increasing corrugation height induces vortex and increases shear zones, thereby reducing water conveyance efficiency. Moderate increase of corrugation pitch and width can enhance water conveyance efficiency and the stiffness of CPSSA. This study advances the knowledge for the design and optimization of CPSSA.

波纹板边墙钢渡槽流场水力学试验与数值研究

波纹板侧壁钢渡槽是一种专门用于输水的水工结构。本文通过实验与仿真相结合的方法研究了流体参数和CPSSA设计参数对流动流体力学的影响。引入水结构效率指标对CPSSA进行优化设计。设计并测试了1:20比例尺的CPSSA模型，并进行了考虑流固耦合的数值模拟。结果表明，水流速度和波纹板对流速分布和边界层厚度有显著影响。波纹高度增大，会产生涡流，增加剪切带，从而降低输水效率。适当增加波纹节距和波纹宽度，可以提高CPSSA的输水效率和刚度。本研究为CPSSA的设计和优化提供了理论依据。

期刊介绍： Engineering Structures provides a forum for a broad blend of scientific and technical papers to reflect the evolving needs of the structural engineering and structural mechanics communities. Particularly welcome are contributions dealing with applications of structural engineering and mechanics principles in all areas of technology. The journal aspires to a broad and integrated coverage of the effects of dynamic loadings and of the modelling techniques whereby the structural response to these loadings may be computed. The scope of Engineering Structures encompasses, but is not restricted to, the following areas: infrastructure engineering; earthquake engineering; structure-fluid-soil interaction; wind engineering; fire engineering; blast engineering; structural reliability/stability; life assessment/integrity; structural health monitoring; multi-hazard engineering; structural dynamics; optimization; expert systems; experimental modelling; performance-based design; multiscale analysis; value engineering. Topics of interest include: tall buildings; innovative structures; environmentally responsive structures; bridges; stadiums; commercial and public buildings; transmission towers; television and telecommunication masts; foldable structures; cooling towers; plates and shells; suspension structures; protective structures; smart structures; nuclear reactors; dams; pressure vessels; pipelines; tunnels. Engineering Structures also publishes review articles, short communications and discussions, book reviews, and a diary on international events related to any aspect of structural engineering.
