Electrochemical Pickling of Steel for Industrial Applications: Modeling

M. Freda[1], A. Giannetti[1], L. Lattanzi[1], S. Luperi[1]
[1]Centro Sviluppo Materiali, Rome, Italy

The electrochemical pickling of steel has two main purposes: 1) To remove thermal oxide; 2) To dissolve chromium-depleted layer, to reinstate the corrosion-resistant properties of the stainless steel; A reliable, flexible and robust 3D model has been made for simulating the steel ... Read More

Simulation of Gravitational Instability During CO2 Absorption in a NaHCO3/Na2CO3 Solution

C. Wylock[1], A. Rednikov[1], B. Haut[1], P. Colinet[1]
[1]Université Libre de Bruxelles (ULB), Transfers, Interfaces and Processes (TIPs), Brussels, Belgium

This work deals with the modeling and the numerical simulation of the CO2 absorption, coupled with a chemical reaction, in an initially quiescent aqueous solution of sodium carbonate (Na2CO3) and bicarbonate (NaHCO3), inside a Hele-Shaw cell. In our Hele-Shaw cell, the liquid fills ... Read More

A Multiphase Porous Medium Transport Model with Distributed Sublimation Front to Simulate Vacuum Freeze Drying

A. Warning[1], J. M. R. Arquiza[1], A. K. Datta[1]
[1]Cornell University, Ithaca, NY, USA

A continuum, porous medium formulation with non-equilibrium sublimation was developed and validated for freeze drying without and with uniform microwave volumetric heating. The model incorporates the effect of Knudsen flow at low pressure and low permeability freeze drying. The ... Read More

Design of a Microreactor for Microwave Organic Synthesis through Microwave Heating Simulations

W. H. Lee[1], K. Jensen[1]
[1]Massachusetts Institute of Technology, Cambridge, MA, USA

We will present the issues of a microreactor setup designed for microwave organic synthesis and demonstrate how COMSOL Multiphysics® is used to understand the mechanism of microwave heating and improve the microreactor design. The RF Module was used for the electromagnetics and solid ... Read More

Numerical Model for Leaching and Transporting Behavior of Radiocesium in MSW Landfill

H. Ishimori[1], K. Endo[2], H. Sakanakura[2], M. Yamada[2], M. Osako[2]
[1]Ritsumeikan University, Kusatsu, Shiga, Japan
[2]National Institute for Environmental Studies, Tsukuba, Ibaraki Prefecture, Japan

This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for ...

Numerical Analysis of Mass Transfer Rate in Droplet Flow at Microscopic Scales new

S. Cito[1], T. Sikanen[1]
[1]Division of Pharmaceutical Chemistry and Technology, Faculty of Pharmacy, University of Helsinki, Helsinki, Finland

Droplet flow at microscopic scale is often used to enhance many pharmaceuticals and industrial processes (i.e. liquid–liquid micro-extraction, nanoparticle synthesis, slow reactions in microfluidic devices, etc.). In all these processes, the mass transfer rate, at the interface between ... Read More

Analysis to Determine Optimum Strain Gauge Locations for SENSEWHEEL new

T. Suzuki[1], C. Holloway[1], S. Taylor[1]
[1]University College London, London, UK

Manual wheelchair users suffer shoulder pain and injury in the long term because of unconscious overuse. The ‘SENSEWHEEL’, which interposes three identical load cells between pushrim and rear wheel, measures the three components of pushing force Fx, Fy and Fz, and axial torque Tx ... Read More

Pump and Ejector Design in Wastewater Treatment Pilot Equipment new

G. Actis Grande[1], A. Pezzin[1], G. Rovero[1]
[1]Politecnico di Torino, Torino, Italy

Ozone treatment is an oxidative process used in wastewater treatment plant to demolish complex organic molecule. In the case of textile industry is required to adequately remove residual color, demolishing the chromophoric bonds or groups in the dye molecules. A useful method for ... Read More

Computational Simulation of Gold Core/Shell Nanostructures for Near-Field Transducers in Heat-Assisted Magnetic Recording new

J. Bennington[1]
[1]Queen's University Belfast, Belfast, Northern Ireland, UK

A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... Read More

Simulation of Microstructured Rolling-Sliding Contacts new

M. Weschta[1], S. Tremmel[1], S. Wartzack[1]
[1]Engineering Design, Friedrich-Alexander-University Erlangen-Nürnberg (FAU), Erlangen, Bavaria, Germany

To reduce friction in lubricated tribological contacts, the surfaces of the contacting bodies can be microstructured to improve lubricating conditions. For lower loaded contacts this approach has already reached industrial applications, e.g. the piston-liner contact. For higher loaded ... Read More
