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 ...

Cobble Sea Defence: Hydraulic Interface Stability of Sand underlying a Single Filter Layer [PDF]
, 2010 A cobble sea defence appears to be an easy constructible protection, with relatively low total costs of ownership. Flume tests show that sand under such single layered constructions is stable. However, it is not exactly known how the hydraulic loading of
