[1]Institute for Industrial, Radiophysical and Environmental Safety (ISIRYM) - Universitat Politècnica de Valencia, Valencia, Spain
[2]Instituto Universitario de Automática e Informática Industrial (AI2) - Universitat Politècnica de Valencia, Valencia, Spain

Microdialysis is a technique of continuous glucose monitoring in diabetic patients. In microdialysis, a saline serum is perfused into a microdialysis probe. Glucose pass from the plasmatic fluid through the porous membrane. The glucose concentration in the dialysate obtained is measured ... Read More

Numerical Simulation of Concentration Polarization to Estimate Gypsum and Calcium Carbonate Scaling on Membrane Surfaces

A. Santafé-Moros[1], J.M. Gozálvez-Zafrilla[1]
[1]Institute for Industrial, Radiophysical and Environmental Safety (ISIRYM) - Universitat Politècnica de Valencia, Valencia, Spain

This paper shows a model to estimate the scaling parameters for reverse osmosis membrane processes. The model takes into account the concentration polarization of ionic species in the membrane channel of spiral-wound modules and the effect of the spacers on the flow. The scaling ... Read More

Modeling and Simulation of Dielectric Barrier Discharge Plasma Reactor for Nitrogen Fixation Reaction

B.S. Patil[1], Q. Wang[2], V. Hessel[2], J. Lang[3]
[1]Eindhoven University of Technology, Eindhoven, The Netherlands
[2]Micro Flow Chemistry and Process Technology, Eindhoven University of Technology, Eindhoven, The Netherlands
[3]Innovation Management, Verfahrenstechnik & Engineering, Evonik Industries AG, Hanau-Wolfgang, Germany

Fixed nitrogen is used in many forms ranging from nitric acid to hydrogen cyanide and is used as such for industrial applications. The reactions to produce these products are highly endothermic and favored by high-temperature processing. The most basic route of chemically fixing nitrogen ... Read More

Food Cooking Process. Numerical Simulation of the Transport Phenomena

B. Bisceglia[1], A. Brasiello[1], R. Pappacena[1], R. Vietri[1]
[1]University of Salerno, Department of Industrial Engineering, Fisciano (SA), Italy

Aim of the study is to determine the influence of some of the most important operating variables, especially humidity and temperature, of drying air on the performance of cooking process of pork meat. The process is simulated using finite elements software COMSOL Multiphysics®. The ... Read More

Modelling of Non-Equilibrium Effects in Solvent-Enhanced Spontaneous Imbibition in Fractured Reservoirs

M. Chahardowli[1], R. Farajzadeh[1] , H. Bruining[1]
[1]TU Delft, Delft, The Netherlands

In fractured reservoirs, much of the oil is stored in low permeable matrix blocks that are surrounded by a high permeability fracture network. Therefore, production from fractured reservoir depends on the transfer between fracture and matrix, which is critically dependent on their ... Read More

2-D Modeling of Underground Coal Gasification (UCG)

S. Mahajani[1], S. Srikantiah[1], G. Samdani[1], A. Ganesh[1], P. Aghalayam[2]
[1]Department of Chemical Engineering, Indian Institute of Technology Bombay, Mumbai, Maharashtra, India
[2]Indian Institute of Technology Madras, Chennai, India

UCG is a process which converts coal to syn gas at the underground coal seam itself. UCG can help meeting the rising energy demand by utilizing coal resources that otherwise would be too deep, or of poor quality, or simply not economical to mine. As UCG takes place, a cavity is formed ... Read More
