Numerical study of effective thermal conductivity of periodic complex structures to be used in HIDiC

Y. AL-MAQALEH1, N. RAIMONDI2, D. ROUZINEAU1, M. MEYER1
1INPT, Toulouse, France
2UPS, Toulouse, France

In this numerical investigation, the effective thermal conductivities (ETC) of periodic complex structures are evaluated. These structures are to be used as packing in Heat-Integrated Distillation Columns (HIDiC). Only high-porosity (>85%) complex structures are considered for ... Mehr lesen

Candy Mercado1
1University of the Philippines, Quezon City, Philippines

The presence of hexavalent chromium in dangerous concentrations in mine wastewater poses a hazard to the environment and emphasizes the development of technology in wastewater treatment is important. This study focused on the simulation of a fixed-bed adsorption column of soil and water ... Mehr lesen

Numerical simulation to improve the H2O-barrier property of films by integration of water absorbers

Jing Tang1, Oliver Miesbauer1
1TUM, Freising, Bayern, Germany

Flexible electronic devices are very sensitive against the ingress of oxygen and water vapor from the atmosphere and therefore must be protected by encapsulation with high barrier films. Typically these films contain at least two or three inorganic barrier layers separated by polymeric ... Mehr lesen

Johan Nordstrand1, Joydeep Dutta1
1Functional Materials, Applied Physics Department, KTH, Sweden

The rapidly increasing world population will dramatically expand the future global freshwater requirements, now making lots of researchers realize the fundamental importance of developing effective desalination technologies. Hence, the emerging capacitive deionization (CDI) desalination ... Mehr lesen

CFD modelling of a carbonation reactor

A. Egedy1, A. Kummer1, T. Varga1, S. Leveneur2
1University of Pannonia, Veszprém, Hungary
2INSA de Rouen, Saint Etienne du Rouvray France

The transition to sustainable production includes the reduction of fossil material usage. Vegetable oil can be used as a reagent to form polyurethane by epoxidation through three major reaction steps, epoxidation, carbonation, and aminolysis. Many attempts have been made to model these ... Mehr lesen
