Numerical Calculations of Ship Induced Waves
Nowadays, various numerical methods are developed to extend computational fluid dynamics in engineering applications. One of the most useful methods in free surface modeling is Boundary Element Method (BEM). BEM is used to model inviscid fluid flow such as flow around ships. BEM solutions employ surface mesh at all of the boundaries. In order to model the linear free surface, BEM can be modifie...
متن کاملDisseminating melanoma cells surf on calcium waves
Dysregulated calcium signaling has been increasingly implicated in tumor dissemination and progression. In a recent study we investigated the mechanism underlying calcium-mediated melanoma invasion and metastasis, and discovered that hyperactive Ca2+ oscillation in melanoma cells promoted invasion and metastasis through promoting invadopodium formation and extracellular matrix remodeling.
متن کاملExtreme Waves and Ship Design
Recent research has demonstrated that extreme waves, waves with crest to trough heights of 20 to 30 meters, occur more frequently than previously thought. Also, over the past several decades, a surprising number of large commercial vessels have been lost in incidents involving extreme waves. Many of the victims were bulk carriers. Current design criteria generally consider significant wave heig...
متن کاملShip Underkeel Clearance in Waves
A method is described for combining squat, heel and wave-induced motion calculations into an overall underkeel clearance (UKC) assessment, based on the “dynamic draft” at all the corners of the ship. Particular attention is given to predicting ship motions in shallow water. The effects of resonant roll, wave spreading and extreme motions are discussed. A general UKC assessment is proposed, vali...
متن کاملLinear “ship waves” generated in stationary flow of a Bose-Einstein condensate past an obstacle
Using stationary solutions of the linearized two-dimensional Gross-Pitaevskii equation, we describe the “ship wave” pattern occurring in the supersonic flow of a Bose-Einstein condensate past an obstacle. It is shown that these “ship waves” are generated outside the Mach cone. The developed analytical theory is confirmed by numerical simulations of the flow past body problem in the frame of the...
