In cooperation with other institutions, GRS adapts and validates the CFX code developed by ANSYS for LWR containment applications. In a severe accident scenario in a LWR large amounts of steam and hydrogen are released into the containment at different locations. To simulate the main phenomena relevant for accident scenarios within LWR containments models, especially the ones provided to CFX by...
Abstract The present study deals with the simulation of filling process in injection molding using Ansys CFX and its experimental validation. For this purpose, an exemplary mold is investigated numerically as well experimentally at different time steps. numerical investigation, a suitable model elaborated CFX, which enables such comparison. In particular, representation viscosity for polymers n...
Exceeding the energy density of lithium−carbon monofluoride (Li−CFx), today's leading Li primary battery, requires an increase in fluorine content (x) that determines theoretical capacity available from C−F bond reduction. However, high F-content carbon materials face challenges such as poor electronic conductivity, low reduction potentials (<1.3 V versus Li/Li+), and/or utilization. This study...
background and purpose: recently, release of pollutants such as pharmaceuticals to the environment becomes one of the most important problems for soil and water. the present study was conducted to introduce walnut shell-based activated carbon (ac) as a new low-cost adsorbent for the removal of cephalexin (cfx) antibiotic from aqueous solutions. materials and methods: this study was conducted in...
A new automated pharmacoanalytical technique for convenient quantification of redox-active antibiotics has been established by combining the benefits of a carbon nanotube (CNT) sensor modification with electrocatalytic activity for analyte detection with the merits of a robotic electrochemical device that is capable of sequential nonmanual sample measurements in 24-well microtiter plates. Norfl...
Green photosynthetic bacteria harvest light and perform photosynthesis in low-light environments, and contain specialized antenna complexes to adapt to this condition. We performed small-angle neutron scattering (SANS) studies to obtain structural information about the photosynthetic apparatus, including the peripheral light-harvesting chlorosome complex, the integral membrane light-harvesting ...
To gain insight into surface processes in plasma processing, basic ion beam experiments are performed on two representative polyatomic-ion species: hydrocarbon ions CHx 1 for deposition processes and fluorocarbon ions CFx 1 for etching processes (x51,2, . . . ). A single ion species is extracted from an inductive plasma via a mass filter and directed onto aluminum surfaces at energies ,150 eV. ...
The goal of this article is to contribute to a more precise discussion of the question whether Lattice-Boltzmann (LB) methods can be regarded as efficient CFD solvers. After a short review of the basic model and recommendable extensions, we compare the accuracy and computational efficiency of two research simulation codes based on the LB and the Finite-Element method (FEM) for incompressible la...
Fluorinated carbon-based thin films offer a wide range of properties for many technological applications that depend on the microstructure of the films. To gain a better understanding on the role of fluorine in the structural formation of these films, CFx systems based on graphenelike fragments were studied by first principles calculations. Generally, the F concentration determines the type of ...
