In a prior publication by the current authors (Akbarzadeh et al., 2023), a distinct phenomenon termed “second pinch-off” was observed for certain scenarios of parallel water entry of equally-sized hydrophobic-hydrophilic spheres. This experimental study examines this event more comprehensively. Experiments with differently-sized spheres are also conducted and analyzed. In the equally-sized cases, two spheres with a diameter of <span><math><mrow><mn>20</mn><mtext>mm</mtext></mrow></math></span>, positioned in a lateral distance of 1.5 times the diameter, are released simultaneously from heights ranging from 25 to 55cm.

In these configurations, the vortex shedding behind the hydrophilic sphere significantly influences the air cavity produced by the hydrophobic sphere. A high-speed photography system, coupled with an image processing technique, is employed to analyze the event dynamics. Additionally, a Particle Image Velocimetry system is utilized to capture the flow field, extracting both velocity and vorticity fields. The analysis demonstrates that a vortex ring forms behind the hydrophilic sphere and causes some waviness in the cavity interface. This vortex ring is shed and migrates towards the cavity wall causing an indentation which grows over time and finally completely severs the air cavity (second pinch-off). Furthermore, the results highlight that the second pinch-off time, in non-dimensional form, correlates linearly with the impact Weber number.

By towing the turbines through a tank against head waves we explore the influence of tip-speed ratio, wave amplitude and wave frequency, on the mean and unsteady rotor and blade loads. Turbine mean power and thrust coefficients in waves agree well with the steady flow coefficients recorded without waves. The dynamic power and thrust coefficients describe paths forming hysteresis loops around mean values when presented against tip-speed ratio defined based on instantaneous rotor-averaged flow speed. Single frequency harmonic fits provide reasonable fits to rotor loads enabling the assessment of loading phase with respect to incident waves. Rotor fluctuating loads increase with wave amplitude and tip-speed ratio, but decrease with wave frequency, with rotor torque showing greater sensitivity to wave conditions than thrust. Analysis of blade root bending moments as a function of wave phase and blade azimuth reveals that flapwise and edgewise load maxima and minima occur in advance of the crests and troughs of the approaching waves, but that the azimuthal locations at which blades experience maxima and minima are functions of wave frequency. Contrary to expectations blade loading is found to be maximum when blades are approximately horizontal which we attribute to spanwise correlation of wave orbital kinematics along blades. As wave frequency is increased, blade load maxima and minima occur closer to top dead centre due to increased vertical decay of wave orbitals. Peak flapwise and edgewise blade loads are found to occur on blade upstrokes and downstrokes respectively which we attribute to the contribution of the vertical component of wave orbitals and rotor-rotor interference. Differences in blade loads of the side-by-side turbines are attributed to hydrodynamic interactions due to the close quarter-diameter spacing between rotors.</div></div>","PeriodicalId":54834,"journal":{"name":"Journal of Fluids and Structures","volume":"133 ","pages":"Article 104259"},"PeriodicalIF":3.4,"publicationDate":"2025-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study is to evaluate the wind-induced response of a long-span truss roof structure under both closed and different open working states. This will be achieved through the utilization of pressure measurement wind-tunnel tests, finite element modelling, and dynamic response analysis. The present study conducts a statistical analysis on the influence of opening rate and opening position on wind load characteristics and wind response. The Welch method and Frequency method are employed to investigate the spectral characteristics of fluctuating wind pressure and the spatial correlation evolution of wind pressure in the low-frequency range. The findings indicate that the introduction of ventilation openings leads to a notable reduction in mean wind load. The presence of these openings, however, leads to an increase in localized wind pressure fluctuations due to the generated prominent turbulence. Secondly, the friction generated during the opening process primarily dissipates low-frequency large-scale vortex energy, thereby leading to a higher frequency distribution of fluctuating wind pressure spectrum. The time-averaged wind response, fluctuating wind response, dynamic response spectrum characteristics, and probability density distribution characteristics of the roof structure are statistically analyzed based on this premise. The results indicate that the variation in wind-induced response of the roof structure aligns with the fluctuation in wind load as a function of opening rate. When the frequency is lower than the dominant frequency, opening ventilation mitigates wind-induced vibration response of the structure; conversely, opening ventilation will amplify wind-induced vibration response of the structure. The windward area of the long-span truss roof structure experiences buffeting. The structural aerodynamic instability occurs in both the rooftop and wake region due to the presence of non-Gaussian, non-self-excited aerodynamic forces and modal vibrations.</div></div>","PeriodicalId":54834,"journal":{"name":"Journal of Fluids and Structures","volume":"133 ","pages":"Article 104268"},"PeriodicalIF":3.4,"publicationDate":"2025-01-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143141300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A three-dimensional nonlinear mathematical model is obtained for a pipe conveying fluid subjected to an external torsional moment. Bending, axial and torsional dynamics are included in the model and nonlinearities up to the cubic order are retained in the equations of motion. The dynamics of the pipe is formulated around the axial and torsional static solutions. The effects of the external torsional moment on the stability of the pipe are characterized as functions of the magnitude and location of the moment. It is shown that there is a critical magnitude, which depends on the location, above which a static instability occurs. Regardless of the magnitude of the torsional moment, it always reduces the critical flow velocity for flutter. While the stability of pipes conveying lighter fluids is shown to be more sensitive to torsional moments applied at the free end, applications at the middle point are more critical for pipes conveying heavier fluids. Depending on the system parameters, divergence and flutter may either coexist, or the system is stabilized over a range of flow velocities before it loses stability again, at higher flow velocities, by flutter.

The flag is positioned at varying gap distances (<span><math><mi>G</mi></math></span>) from the bluff body.

The governing equations in the FRD model are solved by the finite element method (FEM), and the CFD is implemented by the finite volume method (FVM). The vegetation effect is added by introducing body forces into the Reynolds-averaged Navier-Stokes equations as point source terms.

A test case of flow around a single flexible plate was first designed to strictly validate the numerical scheme. The model was then further validated by experimental results of flow with a gently undulating patch of flexible plates.
