| 1 | Computational fluid dynamics modeling of abutment scour under steady current using the level set method显示文摘The scour and deposition pattern around an abutment under constant discharge condition is calculated using a three dimensional(3D) Computational Fluid Dynamics(CFD) model.The Reynolds-Averaged Navier Stokes(RANS) equations are solved in three dimensions using a CFD model.The Level Set Method(LSM) is used for calculation of both free surface and bed topography.The two-equation turbulence model(k-ε and k-ω) is used to calculate the eddy viscosity in the RANS equations.The pressure term in the RANS equations on a staggered grid is modeled using the Chorin’s projection method.The 5th order Weighted Essentially Non-Oscillatory(WENO) scheme discretizes the convective term of the RANS equations.The Kovacs and Parker and Dey formulations are used for the reduction in bed shear stress on the sloping bed.The model also used the sandslide algorithm which limits bed shear stress reduction during the erosion process.The numerical model solution is validated against experimental results collected at the Politecnico di Milano,Milan,Italy.Furthe r,the numerical model is tested for perfo rmance by varying the grid sizes and key parameters like the space and time discretization schemes.The effect of varying bed porosity has been evaluated.Overall,the free surface is well represented in a realistic manner and bed topography is well predicted using the Level Set Method(LSM). | Mohammad Saud Afzal Hans Bihs Lalit Kumar | 2020 | International Journal of Sediment Research2020,35,4: | 4 |
| 2 | Baossi–Warack monogenetic volcanoes, Adamawa Plateau,Cameroon: petrography, mineralogy and geochemistry显示文摘Three monogenetic cones in the Baossi–Warack area, Ngaoundéré, Adamawa Plateau forming part of the Cameroon Volcanic Line(CVL) are documented in this study. Basaltic lavas(<1 km^3) scattered around these vents and restricted volcaniclastic deposits were emplaced by Hawaiian and mild strombolian style eruptions. The lavas are porphyritic, mainly composed of olivine(chrysolite) and clinopyroxene(diopside and augite) phenocrysts and plagioclase(andesine) microphenocrysts. Accessory minerals include titano-magnetite and titano-hematite, nepheline,apatite and amphibole xenocrysts. Sanidine occurs in some samples and sodi-potassic albite in others. Some olivines and clinopyroxenes exhibit resorbed margins and thin reaction rims while plagioclase displays oscillatory zoning, and sieved textures as a result of magma mixing. Whole-rock geochemistry data indicates that the lavas are silica-undersaturated, composed of basanites and basalts, showing little compositional variations(SiO_2: 39.20 wt.%–48.01 wt.%,MgO: 5.29 wt.%–9.70 wt.%). Trace elements patterns of these lavas suggest they are enriched in LILE including Pb,probably due to crustal contamination. REE patterns suggest cogenetic magmas below Baossi 1 and Baossi 2 volcanoes,and distinct sources below Warack volcano and nearby lavas.The lavas studied show affinity to high-μ(HIMU), enriched type Ⅰ(EM1) and Oceanic Island Basalt(OIB)-like mantle signatures and thus indicate a heterogeneous mantle source underneath the vents as noted at other monogenetic and polygenetic volcanoes along the CVL. Primary melts derived from low degrees of partial melting(0.5%–2%) and encountered low rates of fractionation, and crustal contamination coupled with magma mixing. These melts evolved independently through structural weaknesses in the basement. | Anicet Feudjio Tiabou Robert Temdjim Pierre Wandji Jacques-Marie Bardintzeff Vivian Bih Che Edith Ekatah Bate Tibang Caroline Neh Ngwa Fran?ois Xavier Onana Mebara | 2019 | Acta Geochimica2019,38,1: | 2 |
