Effect of Submergence Ratio on Flow Characteristics of Rigid Vegetation Array Haspolat, Emre; Köken, Mete (2024-06-04)
Experimental investigation of the total flow resistance in emergent and submerged rigid canopy flows Haspolat, Emre; Köken, Mete (2024-05-01) In canopy flows, flow resistance mainly originates from vegetation drag and depends on vegetation characteristics and flow conditions. In the present study, a series of experiments were performed in various hydraulic scena...
Influence of submergence ratio on flow and drag forces generated by a long rectangular array of rigid cylinders at the sidewall of an open channel Köken, Mete; Constantinescu, George (2023-06-27) This paper discusses how the submergence ratio, defined as the ratio between the flow depth, D, and the height, h, of the solid rigid cylinders forming the array affects flow and turbulence structure inside and around a re...
Finite volume analysis of dam breaking subjected to earthquake accelerations Mosaddeghi, Farshid; Köken, Mete; Aydın, İsmail (2023-01-01) Because of the complexity of the dam failure mechanism due to earthquakes that occur under the simultaneous influence of hydraulic and seismic forces, a single model has not been obtained so far and this study was conducte...
Effects of patch height on sediment entrainment mechanisms around a rectangular patch of vegetation Köken, Mete; Constantinescu, George (2022-11-08)
NUMERICAL INVESTIGATION OF FLOW AROUND AN ISOLATED PIER ON AN INCLINED SURFACE Köken, Mete; HESAP, EMRE; BOMBAR, GÖKÇEN; ELÇİ, ŞEBNEM; Cardoso, Heleno Antonio (2022-06-26)
An iterative hydraulic design methodology based on numerical modeling for piano key weirs Köken, Mete; Aydın, İsmail; Ademoglu, Serhan (2022-01-01) Piano Key Weir (PKW) is a special type of overflow weir which provides an improved discharge capacity with its increased crest length. Increased discharge capacity makes this weir an attractive alternative in the rehabilit...
Flow structure inside and around a rectangular array of rigid emerged cylinders located at the sidewall of an open channel Köken, Mete (Cambridge University Press (CUP), 2021-01-01) Flow structure inside and around a rectangular array of emerged cylinders located adjacent to the sidewall of an open channel is investigated using eddy-resolving numerical simulations. This configuration is particularly r...
Investigation of velocity field around bridge abutments Yıldız, Burhan; Köken, Mete; Göğüş, Mustafa (null; 2019-06-15)
Approximate methodology to account for effects of coherent structures on sediment entrainment in RANS simulations with a movable bed and applications to pier scour Cheng, Zhengyang; Köken, Mete; Constantinescu, George (2018-10-01) Movable-bed Reynolds-Averaged Navier-Stokes (RANS) simulations of local scour around bridge piers and abutments without ad hoc corrections tend to underestimate scour. This is generally attributed to the inability of RANS ...
