Wave Forces exerted on Submerged Circular Cylinders fixed in Regular Waves

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...

Contractile cell forces exerted on rigid substrates.

Adhesive cells including fibroblasts produce contractile forces to the underlying substrate for their locomotion. Such forces are not only high enough to deform compliant membranes such as silicone but also bend rigid micro-cantilevers. The cell-induced bending of silicon micro-cantilevers was determined using laser deflection during trypsin treatment. The observed cantilever relaxation corresp...

Scattering of Plane Waves on Finite Cylinders with Non-circular Cross-sections

Simulation of Wave Induced Forces on Semi Submerged Horizontal Cylinders Using OpenFOAM Master of Science Thesis in the Master Degree Programme Naval Architecture

The work presented in this thesis documents the simulation of wave induced forces on semi submerged horizontal cylinders in OpenFOAM, utilizing the blending method for generation and damping of waves. The blending method is not included with OpenFOAM and thus required development before it could be employed. Both a linear Airy wave model and a fifth order stokes wave model are implemented. The ...

Traction forces exerted by epithelial cell sheets.

Whereas the adhesion and migration of individual cells have been well described in terms of physical forces, the mechanics of multicellular assemblies is still poorly understood. Here, we study the behavior of epithelial cells cultured on microfabricated substrates designed to measure cell-to-substrate interactions. These substrates are covered by a dense array of flexible micropillars whose de...
