    Abstract Ultrasonic baths and sonochemical reactors are widely used in industrial applications dealing with surface cleaning and chemical synthesis. The processes of erosion, cleaning and structuring of the surface can be typically controlled by changing relevant influential parameters. In particular, in this work, we experimentally investigate the effect of NaCl concentration (0–5.5 mol/L) on the erosion of an aluminum foil under ultrasonic exposure at a frequency of 28 kHz. Special attention is paid to the determination of cavitation zones and their visualization using heat maps. It is found that at low NaCl concentration (0.3 mol/L), the More > Graphic Abstract

    Effect of NaCl Concentration on the Cumulative Strain and Pore Distribution of Clay under Cyclic Loading

    Xinshan Zhuang*, Shunlei Xia, Ruijie Pan

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.2, pp. 447-461, 2024, DOI:10.32604/fdmp.2023.042220

    Abstract Clay, as the most common soil used for foundation fill, is widely used in various infrastructure projects. The physical and mechanical properties of clay are influenced by the pore solution environment. This study uses a GDS static/dynamic triaxial apparatus and nuclear magnetic resonance experiments to investigate the effects of cyclic loading on clay foundations. Moreover, the development of cumulative strain in clay is analyzed, and a fitting model for cumulative plastic strain is introduced by considering factors such as NaCl solution concentration, consolidation stress ratio, and cycle number. In particular, the effects of the NaCl… More >
