Wave Reflection at Submerged Breakwaters
Several types of structures are used in Coastal Engineering with the aim of preventing shoreline erosion, such as groynes, detached breakwaters, submerged breakwaters, etc. Submerged breakwaters have the advantage of their minimal visual impact, which has made them ever more popular (Chang & Liou, 2007). When the incoming waves impinge on a submerged breakwater, a process of energy transformati...
متن کاملEffects of Flow Hydraulics, Pipe Structure and Submerged Jet on Leak Behaviour
The aim of this paper is numerical and experimental study of the effects of flow hydraulics, pipe structure (particularly elastic behaviour) and submerged jet on leak behaviour. In this regard, experimental tests were performed on a high-pressure circulation set up. Experiments were performed on an old steel pipe and a High Density Polyethylene (HDPE) pipe discharged to the atmosphere in a wide...
متن کاملCurvature effects on wave propagation in an infinite pipe
Abstract Advanced research into non-destructive control of industrial pipeworks provides several acoustical methods for inspection of their structural integrity. Applying guided waves is one possible solution to detect and identify different flaws. Many studies have shown the importance of complex waves describing the interaction phenomena at the vicinity of the defects, modeled as geometrical ...
متن کاملTravelling wave states in pipe flow
In this paper, we report numerical calculations of two new travelling wave states with shift and reflect two-fold azimuthal symmetry (S2 symmetry of Wedin and Kerswell (2004)), characterized by a shrinking core towards the pipe center with increasing R. Further, one of these solutions, termed C2, has additional shift and rotate symmetry. We also present arguments to identify all possible scalin...
متن کاملModulation of wave forces on kelp canopies by alongshore currents
The predominant view of the canopy-forming kelp’s mechanical response to water motion is that they sway passively under waves such that they are only rarely stretched out in flow, which reduces relative fluid velocities and decreases the applied force. Such a view is an appropriate first-order approximation but becomes conceptually problematic in the face of the net surface velocities (Stokes d...
