  • Effect of the Bed-Sediment Layer on the Scour Caused by a Jet 
    Taştan, Kerem; Koçak, Peli̇n Pınar; Yıldırım, Nevzat (2016)
    Scour caused by a water jet impinging the bedsediment layer is a significant concern for hydraulic engineers. Although several studies investigated the maximum scour depth on the non-cohesive bed-sediment layer, the effect ...
  • Effective intake for critical submergence in the case of more than one intake 
    Taştan, Kerem; Yıldırım, Nevzat (2017)
    The available potential flow solution methods over-estimate the number of effective intake for the prediction of critical submergence in the case of multiple intakes of identical level without partition walls located on ...
  • Effects of intake geometry on the occurrence of a free-surface vortex 
    Taştan, Kerem; Yıldırım, Nevzat (ASCE-AMER Soc Civil Engineers, 2018-04)
    Both the profile and orientation of an intake entrance basically determine the characteristics of the flow (especially the velocity distribution and therefore the hydraulically developed subsurface depressions) toward the ...
  • Flow Rate along the Length of the Swirling Vortex Axis at an Intake 
    Taştan, Kerem; Yıldırım, Nevzat (2021)
    In this study, the characteristics of the flow in the region of swirling vortex are examined. The potential flow model based on the summing infinite number of spherical sinks along the vortex core is introduced to predict ...
  • Improved Equations for the Profile of a Vertical Air-Core Vortex 
    Taştan, Kerem; Yıldırım, Nevzat (2023-05)
    The available formulas for the profile of a vertical non-air-entraining vortex are not practical because they involve unknown parameters and need measurements of the local viscous-core radii across the height of the air-core ...
  • Occurrence of a swirling vortex without an intake 
    Taştan, Kerem; Yıldırım, Nevzat (2021)
    In this study, mechanisms that cause the occurrence of a swirling vortex without an intake are explained. There are more than one different reasons which may cause the occurrence of an aircore vortex or a swirling-vortex ...
  • Su alma ağzı giriş şeklinin hava girişli çevrinti üzerindeki ölçek etkisi 
    Taştan, Kerem; Yıldırım, Nevzat (2018)
    Su alma ağzı giriş şekli, ağız üzerinde su yüzeyinde oluşabilecek hava girişli çevrintinin karakteristiklerini belirlediğinden ağza ait kritik batıklık üzerinde bazı etkilere sahiptir. Bu etkiler hız dağılımı etkisi ve ...
