Lithium-carbon monofluoride (Li/CF x ) D-sized battery cells discharged at very low rates (C/1800) were found to deliver inconsistent capacities. These effects be absent as the discharge rate was increased C/600. Destructive physical analysis of C/1800 confirmed corrosion, manifesting preferential utilization Li anode around copper current collector, discoloration remaining excess Li, and more ...

Abstract Using the Design of Experiments methodology ( Response-Surface Methodology and Derringer's Desirability Function ), a simple, fast robust RP-HPLC method was developed for analysis enrofloxacin (EFC), its impurity A (fluoroquinolonic acid, FQ) B (ciprofloxacin, CPX). Gradient elution samples performed on Zorbax Eclipse XDB C18 column (150 × 4.6 mm, 3.5 μm) with mobile phase consisting 3...

Detailed computational simulations of turbulent flows and pollution dispersion in city canyons have been carried out using the computational fluid dynamics package CFX-5, which is capable of using unstructured meshes and a variety of turbulence closure schemes. The simulations have been done for city canyons with simple to complex structures. As a validation of CFX-5, a roof garden test is cond...

We report on results from an interdisciplinary research project of computer scientists, mechanical engineers and numerical analysts from industry and academia. We have designed and implemented a portable distributed memory parallel version of CFX-TfC, a state of the art computational fluid dynamics simulation software package that features finite volume discretization on unstructured hybrid gri...

In this paper, performance of centrifugal pump as turbine (PAT) is investigated numerically. Three different specific speeds are considered and three pumps are designed using diagrams from catalogues and CFturbo V.9 software. Next, models are analyzed by Ansys CFX 16 software and results are compared with those of CFturbo software. Also, a mesh study analysis for one case is performed in order ...
