Reactive Transport Modeling of CO2 in Carbonate Rocks: Single Pore Model

P. Agrawal [1], J. Koskamp [1], A. Raoof [1], M. Wolthers [1],
[1] Utrecht University, Utrecht, The Netherlands

Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the ... Read More

Model Based Stimulus Experiments to Improve Biological Wastewater Treatment Performance

N. Do [1], M. Stich [1],
[1] Non-linearity and Complexity Research Group, System Analytics Research Institute, School of Engineering and Applied Science, Aston University, Birmingham, United Kingdom

The municipal wastewater treatment in a sustainable context requires a smart technology in which an optimal combination of the ecological status and energy demand can be achieved. The integration of electron conductive materials into a traditionally constructed wetland (CW) has been ... Read More

Predictive Model for UV Light Irradiation and PCO Reaction Kinetics in a Photocatalytic Reactor

S. Denys [1], J. Roegiers [1], J. van Walsem [1],
[1] University of Antwerp, Antwerp, Belgium

A novel type of photocatalytic reactor, i.e. parallel flow tube reactor (PFTR) is presented for the degradation of indoor air pollution with UV-light. A Multiphysics model was developed in COMSOL Multiphysics® to predict the steady-state behavior under different inlet concentrations and ... Read More

Sensitivity Analysis of CPP’s for Solvent Removal Process of a API-Protein Bonded Nano-Suspension

C. C. Huang [1], T. Liu [1], F. Faassen [1],
[1] Teva Pharmachemie B.V., Haarlem, The Netherlands

Solvent extraction and evaporation is a widely used unit operation in the manufacturing of micro and nano-particles. Due to the weak bond of the API to the protein, the product is highly sensitive to temperature, mechanical mixing and extraction/evaporation rate. A slow extraction ... Read More

Iron Ore Sintering Process Model to Study Local Permeability Control

Y. Kaymak [1], T. Hauck [1], M. Hillers [2],
[1] VDEh Betriebsforschungsinstitute GmbH, Düsseldorf, Germany
[2] Shuangliang Clyde Bergemann GmbH, Ratingen, Germany

The iron ore sintering process prepares fine iron ore for the blast furnace process. A mixture consisting of iron ore, coke (fuel) and additives is ignited at the top and air is sucked from below to move a combustion front down through the bed. Most of the sintering plants use ... Read More

3D Unsteady CFD with Heat and Mass Transfer Simulations of Solar Adsorption Cooling System for Buildings

W. Yaici [1], E. Entchev [1], J. Ranisau [1],
[1] CanmetENERGY Research Centre, Natural Resources Canada, Ottawa, ON, Canada

In recent years, extensive attention has been paid on the application of solar cooling for buildings. Amongst cooling technologies, low-temperature solar-driven adsorption cooling systems are emerging viable alternatives to electricity-driven vapour compression systems. They seem to have ...

Electrochemical Machining with Nonsymmetric Suction of Electrolyte Flow

M. Hashiguchi [1], D. Mi [1],
[1] Keisoku Engineering System Co. Ltd., Tokyo, Japan

In electrochemical machining process, it is very important to control electrolyte flow field to remove contamination such as slug, or gas to be generated by the machining process as well as heat control for electrolyte, machining tool and work piece. To reduce the overcut of workpiece, ... Read More

Simulation of Molecular Transport of an Electroporated Cell using COMSOL Multiphysics®

J. V. D. Jayasooriya [1], D. Nawarathna [1],
[1] Department of Electrical and Computer Engineering, North Dakota State University, Fargo, ND, USA

Electroporation is a highly efficient cellular transfection method which is used to inject molecules into living cells. The electroporation involves creating temporary pores in cell membranes using an electrical field. It has been successfully utilized in medicine and biology for ... Read More

Virtual Design of a Four-Bed Molecular Sieve for Exploration

T. Giesy [1], R. Coker [1], J. Knox [1], B. O'Connor [1],
[1] NASA Marshall Space Flight Center, Huntsville, AL, USA

Aboard the International Space Station, carbon dioxide is removed from the atmosphere using a four-bed adsorptive separation process, referred to generally as a 4-Bed Molecular Sieve (4BMS). Experience with the current 4BMS design in space has led to a list of areas for improvement for a ... Read More
