Numerical simulations of wave breakings around a wedge- shaped bow
Flows around a wedge-shaped bow are simulated with the aim of investigating the wave breaking mechanism and small scale features of ship bow waves. The wedge geometry used in the experimental study of Waniewski et al. (2002) is chosen with the flow conditions at Re = 1.64×10 5 and Fr = 2.93. The bow wave structure, wave breaking process and air entrainment are studied. The predicted overall bow...
متن کاملEffect of Wedge-Shaped Deflectors on Flow Fields of Dual-Stream Jets
The effect of wedge-shaped fan flow deflectors on the mean and turbulent flow-fields of dual-stream jets is investigated. Several wedge-shaped deflector concepts were used to create asymmetry in the plume of a dual-stream jet issuing from a scaled down version of the NASA Glenn ‘5BB’ bypass-ratio 8 turbofan nozzle. The deflector configurations comprised internal and external wedges with and wit...
متن کاملCasimir densities for wedge-shaped boundaries
The vacuum expectation values of the field squared and the energy-momentum tensor are investigated for a scalar field with Dirichlet boundary conditions and for the electromagnetic field inside a wedge with a coaxial cylindrical boundary. In the case of the electromagnetic field perfectly conducting boundary conditions are assumed on the bounding surfaces. By using the Abel-Plana-type formula f...
متن کاملCFD Hydrodynamics Analysis of Syngas Flow in Slurry Bubble Column
In this paper, a CFD model of syngas flow in slurry bubble column was developed. The model is based on an Eulerian-Eulerian approach and includes three phases: slurry of solid particles suspended in paraffin oil and syngas bubbles. Numerical calculations carried out for catalyst particles, bubble coalescence and breakup included bubble-fluid drag force and interfacial area effects. Also, the ef...
متن کاملFlow Field of a Dual-Stream Jet with External Wedge-Shaped Deflector
The research effort is a Reynolds-Averaged Navier-Stokes (RANS) investigation that looks at the flow-field and performance of a bypass ratio 8 nozzle with an external wedgeshaped noise suppressor, simulating the exhaust of a turbofan engine at takeoff conditions. Peak turbulence was reduced by the wedge on the side opposite the deflector, and it was increased in the initial region of the jet be...
