摘要:... This paper proposes a computational model for the numerical simulation of the material transport inside the pressure chamber of EPB machines. The governing equations of the soil flow are discretized by using the Finite Element (FE) method and the Fractional Step (FS) scheme. ...

摘要:... The migration rate of bedforms, such as ripples and dunes, in these environments is important in determining bed material transport rates to inform and assess numerical models of sediment transport and geomorphology. However, these models tend to ignore parameters describ...

摘要:Abstract(#br)Radioactive material transport packages for certain forms of radioactive materials are designed to withstand a 9-meter accident drop onto an essentially rigid surface in accordance with the IAEA regulations SSR-6. This study presents a framework for dynamic analysis ...

摘要:... Annually repeated surveys of the stream channel — combined with bed material tracer studies in 2006 and 2007 — indicate that the channel has become unstable and that the bed material transport dynamics have changed since the fire. Using these data, the morphologic ch...

摘要:... From the overall integrated pattern of their orientation, we were able to determine Titan’s global material transport vectors. The analysis indicates that, in both the northern and southern hemispheres, materials from 0 to 35 deg latitude are transported poleward to a bel...

摘要:... The bight is a nondepositional area, and all material produced in its water column, from erosion of strata at the seafloor and cliffs, and delivered by rivers, is transported near the seafloor to the depositional areas of the Arkona, Bornholm and Gdansk basins. In this con...

摘要:Abstract(#br)Research in the 1990s showed that bed‐material transport rates could be estimated at the reach scale in both one‐dimension and, over small spatial scales (10s of m), in two‐dimensions. The limit on the latter was the spatial scale over which it was possibl...

摘要:Abstract(#br)Material transport in Al/Ti-finger electrodes on LiNbO 3 substrates of power-loaded surface acoustic wave (SAW) structures were investigated under microscopic observation with respect to stress-induced material transport. Additionally, investigations were carried out...

摘要:Abstract(#br)Bed features were mapped using a thermal depth recorder and a side-scan sonar in the Changjiang (Yangtze) Estuary, and flows were observed and bed surface materials were sampled to investigate bed material transport pathways. Distinct scales and dimensions of dunes...

摘要:Abstract(#br)Heat and material transport processes caused by convective adjustment and mixing are important in modeling of Venus’ atmosphere. In the present study, microscale atmospheric simulations near the venusian surface were conducted using a Weather Research and Foreca...
