Abstract. In this case study, we present the implementation of a FEM-based numerical pore-scale model that enables to track and quantify the propagating fluid-fluid interfacial area on highly complex μ-CT obtained geometries. Special focus is drawn to the reservoir specific capillary pressure (pc)- wetting phase saturation (Sw)- interfacial area (awn)- relationship. The basis of this approach are high resolution μ-CT images representing the geometrical characteristics of a georeservoir sample. The successfully validated two-phase flow model is based on the Navier-Stokes equations, including the surface tension force in order to consider capillary effects for the computation of flow and the phase field method for the emulation of a sharp fluid-fluid interface. In combination with specialized software packages, a complex high resolution modeling domain could be obtained. A numerical workflow based on REV-scale pore size distributions is introduced. This workflow aims at the successive modification of model and model setup for simulating such a type of two-phase problem on asymmetric μ-CT-based model domains. The geometrical complexity is gradually increased starting from idealized pore geometries until complex μ-CT-based pore network domains, whereas all domains represent geostatistics of the REV-scale core sample pore size distribution. Finally, the model could be applied on a complex μ-CT-based model domain and the pc-Sw-awn relationship could be computed.

Among the whole ship unloading process, how to effectively and conveniently put the bulk into the ship-unloader is often a big and key problem. This article advance a new equipment to solve the problem—Screw-gas Bulk Sucking and Taking Equipment, which applies both the theory of vertical screw conveyor and the theory of pneumatic handling. The author describes the constitution of the equipment and explains the working principles in detail, by thus pointing out the superiorities of the equipment, such as low clearing-up, little dust removal, simple construction and convenient maintenance. The article also brings tentative data for proof. The article gives a good solution by providing with a brand-new equipment—Screw-gas Bulk Sucking and Taking Equipment, which applies both the theory of vertical screw conveyor and the theory of pneumatic handling. It constitutes of 3 parts; respectively from bottom to above they are: Centrifugal force Separating Part, Screw Lifting Part and Pneumatic Conveying Part. Granular material is drawn into the equipment in the form of gas-solid two-phase flow by the Atmospheric pressure, and then helically rises in the Centrifugal Force Separating Part which is an inverted cone. The material would be separated from the two-phase flow by the effect of centrifugal force and then be lifted in the Screw Lifting Part. The gas flow with the very little remained material would be drawn into the blower. By thus Screw-gas Bulk Sucking and Taking Equipment could take the material and put it to the next conveying process conveniently and efficiently with the superiorities of low clearing-up, little dust removal, simple construction and convenient maintenance.
