Hydraulic Performance of Alginate-Based Bentonite
Geo-Congress 2022, 2022 Bentonite clay is widely used as a hydraulic barrier in geosynthetic clay liners and cut-off walls. The interaction of the clay with divalent electrolytic solutions such as Ca2+ or Mg2+ deteriorates its sealing properties. The treatment of bentonite with polymers has improved its hydraulic properties; however, sustainability concerns have led to the ...

Hydraulic Performance and Energy Dissipation Mechanism Analysis of the Tesla-Shaped Emitter
Energies, 2023 In this paper, a tesla-shaped emitter is proposed based on the structure of the “tesla valve” as the source of inspiration, so that the water flow in the channel would produce a variety of energy dissipation phenomena, such as diversion, hedging, and ...
