Use is made of Onsager’s hydrodynamic equation to derive the vibration spectrum of the vortex lattice in d-wave superconductor. In particular the rhombic lattice (i.e. the 45 tilted square lattice) is found to be stable for B > Hcr(t). Here Hcr(t) denotes the critical field at which the vortex lattice transition takes place. Typeset using REVTEX 1 Since the discovery of the triangular vortex la...

Top tensioned risers (TTRs) and steel catenary (SCRs) have been widely used in the field of marine engineering. They are commonly to transport fluids from subsea wells surface platforms. Under action ocean currents, these often subjected vortex-induced vibrations (VIVs), which might lead serious fatigue damage. In this study, VIV around TTR SCR were numerically simulated using computational flu...

Abstract As bridge spans stretch, the structure becomes more flexible and susceptible to dynamic wind effects causing harmful wind-induced vibration. The biggest issue with design of long-span bridges is possibility vibration caused by vortices. This study examines mechanism decrease in amplitude vortex-induced for box girder using a flap countermeasure. Aerodynamic countermeasures such as have...
