A numerical investigation of the vortex-induced vibration (VIV) in a side-by-side circular cylinder arrangement has been performed two-dimensional laminar flow environment. One cylinders is elastically mounted and only vibrates transverse direction, while its counterpart remains stationary uniform stream. When gap ratio sufficiently small, flip-flopping phenomenon can be an additional time-dependent interference to field. This was reported experimental work Bearman Wadcock [“The interaction...
In this work, the coupled dynamics of gap flow and vortex-induced vibration (VIV) a side-by-side (SBS) arrangement two circular cylinders is numerically investigated at Reynolds numbers $100\leqslant Re\leqslant 500$ . The influence VIV incorporated by allowing one to vibrate freely in transverse direction, which termed as vibrating (VSBS) arrangement. A comparative three-dimensional study performed between stationary (SSBS) VSBS arrangements examine characteristics complex coupling flow....
The hydrodynamic and thermal characteristics of a freely vibrating circular cylinder subject to cross buoyancy are numerically investigated at low Reynolds numbers. structural responses onset vortex-induced vibration (VIV) documented over range parameter space, 2.0≤ reduced velocity (Ur) ≤10.0, 0.7≤ Prandtl number (Pr) ≤10.0 0.5≤ Richardson (Ri) ≤2.0. fluid coefficients chosen as (Re)=100, mass ratio (m*)=10.0, damping (ζ)=0.01.

The fluid–thermal–structure interaction of three identical, heated circular cylinders in tandem with a variable spacing ratio ranging from 4.0 to 10.0 is numerically investigated using the finite element method this work. vibration response and vorticity–temperature distribution are examined at Prandtl number Pr = 0.71 Reynolds Re 150 reduced velocity range 1.0 ≤ Ur 15.0. numerical results indicate that temperature generally follows vorticity clusters, presenting distinct gradient wake. Four...
The characteristics of laser-induced periodic surface structures are investigated after laser irradiation with a pulse duration (10 ps) under certain fluence (0.27 J/cm2) and number (N = 50–2000). In the experiments, at lowest pulses, ultrafine ripples observed sub-200-nm spatial periods an orientation parallel to polarization direction. With increasing number, chain events that has been consists followed by transformation towards regular perpendicular direction holes finally breaking...
In natural convection (high Richardson number Ri), a high Prandtl (Pr) leads to thinner thermal boundary layers, enlarging the gradient and hence enhancement of buoyancy effect. forced (low Pr introduces thicker velocity layers. mixed scenarios, where both are significant, interaction between Ri determines resultant flow pattern heat transfer characteristic. Three tandem circular cylinders with an identical spacing ratio 4.0 in flows were numerically investigated by using finite element...
Abstract System identification is crucial to predict the maneuverability of ship. In this work, ε-support vector regression (ε-SVR) implemented identify hydrodynamic derivatives Abkowitz maneuver model. A proposed technique, batch learning, with addition Gaussian white noise reconstruct samples and alleviate parameter drift in system ship maneuvering The predicted results are compared obtained from Planar Motion Mechanism (PMM) test. Standard maneuvers, 35° turning circle, 10°/10° 20°/20°...
Abstract All concrete structures contain reinforcement spacers, and deep sections can be affected by bleeding segregation without displaying visible indications during casting. However, their effects on mass transport long-term durability are not well studied. In this paper, reinforced columns were prepared with plastic cementitious spacers to achieve 50 mm cover, compacted at different vibration frequencies durations. 28d cured samples extracted along the height, conditioned equilibrium (21...
The fluid–thermal–structure interaction of a heated circular cylinder is numerically investigated at Pr = 0.71, Re 60–160, and Ri 0–2.0 in this article using the stabilized finite element method. heat convection characteristics along cylinder's surface both forced mixed subject to cross buoyancy are discussed linked fluid instabilities. Additionally, hydrodynamic time frequency domains according strength thermal buoyancy. Multiple harmonics coefficients identified from their domains....
