Abstract: Understanding the air demand of a hydraulic jump in a closed conduit is important in hydropower operations and urban sewer designs. In this study, physical experiments are described to study flow regimes and the air demand ...

Abstract: The theory of viscoelastic collision mechanics is used to explore the rebound and adhesion mechanisms of single aggregates in shotcrete at the meso-level in this study. Abrasive balls with different radiuses were used, ...

Abstract: The prevailing social-spatial disorder within urban settings has become pervasive, particularly in the misalignment between policy formulation and social perception. This underscores the potential for effectively promoting ...

Abstract: Supersaturated total dissolved gases (TDGs) generated by dams can cause gas bubble trauma and mortality in fish in downstream waters. In this study, we evaluated air entrainment and generation of supersaturated TDG at two ...

Abstract: Section contractions in rivers often induce accelerated flows in nature, exerting substantial influence on the swimming behaviors of various fish species. This study focuses on the undulatory swimming strategies of fishes ...

Abstract: This paper presents an analytical study of mass transfer from a single bubble rising in stagnant water and its size variation. A model for bubble–water mass transfer was established and validated using the experimental ...

Abstract: The use of permselective spacers in reverse electrodialysis (RED) stack introduces a more severe concentration polarization phenomenon at membrane–solution interfaces in spite of effectively suppressing the spacer shadow ...
