Flow Field Analysis of Cutter Head for Cutter Suction Dredgers
For a cut ter suction dredger, exploring slurry formation mechanism plays an important role for improving the dredger’s efficiency and performance. In order to optimize the dredger’s working parameters, the flow field is simulated for the cutter head of a cutter suction dredger in this study. First, Cutter’s 3D model is const ructed by 3D Modeling software after necessary parameters are collect...
متن کاملSuction of splash after impact on dry quick sand
It is well known that a splash occurs when an object impacts at high velocity on a liquid’s surface. If the impact is fast enough, surface tension and air pressure gradients pull the crown-shape splash all the way towards the axis of symmetry, making it to collapse and seal the surface. In this paper we show that splash and surface sealing are also observed in impacts on soft, dry sand. We obse...
متن کاملFeeding Kinematics, Suction, and Hydraulic Jetting Performance of Harbor Seals (Phoca vitulina)
The feeding kinematics, suction and hydraulic jetting capabilities of captive harbor seals (Phoca vitulina) were characterized during controlled feeding trials. Feeding trials were conducted using a feeding apparatus that allowed a choice between biting and suction, but also presented food that could be ingested only by suction. Subambient pressure exerted during suction feeding behaviors was d...
متن کاملThe benefits of planar circular mouths on suction feeding performance.
Suction feeding is the most common form of prey capture across aquatic feeding vertebrates and many adaptations that enhance efficiency and performance are expected. Many suction feeders have mechanisms that allow the mouth to form a planar and near-circular opening that is believed to have beneficial hydrodynamic effects. We explore the effects of the flattened and circular mouth opening throu...
متن کاملInfluence of Impeller Suction Specific Speed on Vibration Performance
The most commonly used hard limitation for pump suction specific speed is 11,000 (US units). This hard limit grew out of the recommendations from a 1982 reliability study by J.L. Hallam (Hallam 1982). Concomitant testing of the vibration performance of an OH2 4x6-11 pump was made with impellers designed for different suction specific speeds (Lobanoff and Ross 1985). This study showed that all t...
