Numerical analysis of jet-induced vortices in high-head stepped spillways with a PKW crest using the Omega–Liutex method [PDF]

AIP Advances
This study investigates the flow characteristics and energy dissipation mechanisms of a high-head stepped weir equipped with a piano key weir (PKW) crest, focusing on vortex structures along the flume steps.

EXPERIMENTAL COMPARISON OF FLOW ENERGY LOSS IN TYPE-B AND -C TRAPEZOIDAL PIANO KEY WEIRS (PKWS)

Journal of Engineering and Sustainable Development
As non-linear weirs with a high flow rate, Piano Key Weirs (PKWs) have attracted the attention of water engineers in recent years. Given the limited information available on the energy losses of these weirs, it is important to investigate the energy ...

Experimental Investigation of Local Scour Downstream of a Type B Piano Key Weir on Sand and Gravel Bed Materials [PDF]

علوم آب و خاک
Piano key weirs are a new form of labyrinth weirs and exhibit nonlinear characteristics. Due to their high efficiency regarding flow capacity, it is crucial to investigate local scour and identify solutions to mitigate it.

Piano Key Weir Head Discharge Relationships

, 2011
A piano key (PK) weir is a type of nonlinear (labyrinth-type) weir developed specifically for free-surface flow control structures with relatively small spillway footprints. Currently, no generally accepted standard PK weir design procedure is available.

Investigating the discharge characteristics over a piano key weir with varying key slope and key width ratios under varying discharges

Journal of Hydrology and Hydromechanics
The objective of the present study was to investigate the effect of inlet to outlet key slope ratios (Si/So), inlet to outlet key width ratios (Wi/Wo) and head over the weir on the coefficient of discharge (Cpkw) of type-A trapezoidal piano key weir ...

Numerical study on discharge capacity of piano key side weir with various ratios of the crest length to the width

Open Engineering
A side or lateral weir can be defined as a longitudinal weir put in parallel to the main flow direction. A piano key side weir (PKSW) is one of the various side weirs used to control flow level, flow diversion, and flood harm prevention in dams and ...
