Tunable capillary-induced attraction between vertical cylinders.
Deformation of a fluid interface caused by the presence of objects at the interface can lead to large lateral forces between objects. We explore these fluid-mediated attractive force between partially submerged vertical cylinders. Forces are experimentally measured by slowly separating cylinder pairs and cylinder triplets after capillary rise is initially established for cylinders in contact. F...
متن کاملScattering by rings of vertical cylinders
It is 25 years since the publication of “Linton & Evans” [1] on “The interaction of waves with arrays of vertical circular cylinders”; it is their most cited joint work. The paper describes an exact method in which separation of variables and addition theorems are combined, leading to an infinite system of linear algebraic equations. The method itself is much older, and goes back to a paper by ...
متن کاملWave Scattering from Vertical Surface-Piercing Cylinders
This thesis describes new laboratory observations concerning the interaction between a series of steep incident waves and vertical, surface piercing, cylinders. The motivation for the study arose as a result of wave impact damage sustained to the undersides of several concrete gravity-based structures in the northern North Sea. Earlier work, Swan et al., (1997), demonstrated that in the case of...
متن کاملPneumatic cylinders: modelling and feedback force-control
In this paper, we model, analyze, and control an experimental set-up of a servo pneumatic cylinder. The dynamic behaviour of pneumatic actuator systems is dominant by nonlinear functions. First, a mathematical model for the pneumatic system is derived. Secondly, we investigate the mathematical properties of this model and show boundedness and positiveness of certain variables. Thirdly, we prove...
متن کاملEstimation of Hydrodynamic Force on Rough Circular Cylinders in Random Waves and Currents (RESEARCH NOTE)
Most of the Codes of Practice (API, BSI, DnV, NPD) uses Morison's equation to estimate hydrodynamic loads on fixed and moving offshore structures. The significant difference in the prediction of the loads mainly arises from the assumption of the values of hydrodynamic coefficients. In this paper by analysing a full scale set of data in large KC's numbers collected from Delta Wave Flume in the N...
