... turbulence model and the Schnerr-Sauer cavitation model have been implemented to analyze the hydrodynamic performance of the cavity flows. Research suggests that the placement of a small obstacle can inhibit the region of cavitation and restrain the shedding of sheet cavitation. Moreover, the existence...

... for Very Large Floating Structures (VLFSs) (Wang et al., 2008). A fundamental feature of a VLFS is its structural flexibility, resulting from the existence of large horizontal dimensions compared to its vertical one. Thus, the elastic response of a VLFS is more dominant compared to its rigid body motions...

..., P.R. China ABSTRACT This study is focused on influence of small-scale cylinders on the motion response under the wave action so that the response can be forecast more exactly. A mooring Truss Spar platform is calculated, and the numerical results demonstrate that the existence of the small-scale...

... ABSTRACT The disastrous geology survey in water areas for underwater pipeline construction has been finished with the acoustic strata profile technique. The strata profile has been obtained, which shows the bedrock is consecutive and no fault exists in the exploration area. The existence...

... ABSTRACT In the plasticity chart, non-Japanese clays are distributed above the A line, whereas Japanese clays are distributed widely along the A line. To elucidate the cause of this difference, we focused on the existence of diatom microfossils, and investigated changes in soil plasticity...

... ABSTRACT As the development of investigation on the deepwater oil-gas resources, it has become a controversial issue whether asphaltene deposition exists in deepwater oil pipelines. Based on the related researches, this paper studies on the main factors such as temperature, pressure and oil...
