Estimation 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...
متن کاملMetachronal waves in a chain of rowers with hydrodynamic interactions.
Hair-like appendages called cilia on the surface of a microorganism such as Paramecium or Opalina beat highly synchronized and form so-called metachronal waves that travel along the surfaces. In order to study under what principal conditions these waves form, we introduce a chain of beads, called rowers, each periodically driven by an external force on a straight line segment. To implement hydr...
متن کاملHydrodynamic effects in density waves of granular flows
Granular flows in a narrow pipe are studied numerically by the model taking account of hydrodynamic effects of fluid surrounding particles. In the simulations density waves are observed over the wide range of the Stokes number, which represents the inertial effect of particles. The mechanisms of formation of the density waves are considered and two types of density waves, which are observed in ...
متن کاملData Analysis Methodologies for Hydrodynamic Experiments in Waves
Abstract: This paper presents the methodologies developed in order to provide quality control and analyze the data acquired in hydrodynamic seakeeping experiments of physical models in waves. In such experiments, the data files consist of wave elevations and directions, loads, motions, velocities and accelerations for one or multiple bodies. Additionally, mooring, slamming, sea-fastening, fende...
متن کاملSpontaneous generation of spiral waves by a hydrodynamic instability
The coiling of a thin filament of viscous fluid falling onto a surface is a common and easily reproducible hydrodynamic instability. Here we report for the first time that this instability can generate regular spiral patterns, in which air bubbles are trapped in the coil and then advected horizontally by the fluid spreading on the surface. We present a simple model that explains how these beaut...
