Abstract: Vortex-induced vibration (VIV) of multiple circular cylinders elastically connected together in a side-by-side arrangement subject to steady flow is investigated numerically at a low Reynolds number of 150 and a mass ratio of 2. Simulations are conducted for two-, five- and ten-cylinder systems over a wide range of reduced velocities. The aim of the study is to identify the high-amplitude response range of the reduced velocity for the multiple... More

Abstract: Climate change can alter the status quo of the world as we know today. Water resources may also be influenced by these plausible impacts. The common perception is that these changes may exacerbate the situation of water resources in arid and semi-arid regions, such as the Middle-East, which are experiencing mild to severe water stress due to limited water availability and growing water demands. In that spirit, this study aims to investigate the... More

Abstract: Pre-stressed structure and its application for civil engineering. Specificity of external loads of ships. Corresponded specificity of controllable pre-stressing. An example of pre-stressed structure and an decreasing estimation of its mass (about 10% of the full displacement). Possibility of wider application. More

Abstract: A three dimensional model to predict the hydro-mechanical state of unsaturated and deformable material during hot air drying has been proposed. The material viscoelastic behaviour was formulated using Bishop’s effective stress theory for partially saturated material using the liquid saturation as the Bishop parameter. The hydro-thermal and mechanical equations were coupled by the fluid pressure and the solid matter velocity. The model was... More

Abstract: The independent LNG (Liquified Nature Gas) containment is widely used for small or medium-sized LNG carrier and ship using LNG as fuels. The common tank pattern includes single-spherical-cylindrical tank and double-spherical-cylindrical tank, which is the key to design the hull structure and its support. The support is designed to connect the hull structure and LNG tank. Its main functions are heat transferring and force loading. This paper... More
