Simulation of the Oxygen Supply of Osteoblastic Cells in Dynamic 3D Cell Cultures

P. Elter[1]
[1]University of Applied Sciences Mittelhessen, Germany

In biotechnology and medicine, cells are frequently grown on scaffolds with a three-dimensional channel structure. The oxygen and nutrient supply of the cells is realized by a medium flowing through the channels of the scaffolds. However, it is often difficult to obtain a confluent ... Read More

Coupling Non-Newtonian Fluid Flow and Heat Transfer Inside a Scraped Surface Heat Exchanger

A. Plana-Fattori[1], D. Flick[1]
[1]UMR 1145 Ingénierie Procédés Aliments, INRA, AgroParisTech, Université Paris-Saclay, France

Scraped-surface heat exchangers (SSHEs) handle products that are viscous, that contain particles, and that tend to deposit on the heat transfer surface. The rotating scraper blades continuously remove any deposition on the heating or cooling surface, thereby maintaining the efficiency of ... Read More

Experimental Validation of a Multidimensional Model for an Indirect Temperature Swing Adsorption Unit

T. Ried[1], O. Hinrichsen[2]
[1]Linde AG, Germany
[2]Technical University of Munich, Germany

Temperature Swing Adsorption (TSA) processes are applied for the removal of impurities from various gas streams. The limiting factor of a TSA process is the regeneration step, which is characterized by long heating and cooling times. To reduce the regeneration time, indirectly heated and ... Read More

Modelling the Diffusion/Counter Diffusion of Oxygen and Solutes in Low Density Steels

J. Isaacs[1]
[1]WMG, The University of Warwick, United Kingdom

Low Density Steels (LDS) mostly have additions of aluminum and/or manganese to reduce their weight and to obtain steel grades with various microstructures. The automotive industry is keenly interested in the development of LDS for reducing CO2 emissions by increasing fuel efficiency, ... Read More

Morphological Evolution of a Single Droplet Drying at High Temperatures

T. Nguyen[1], M. Ali[1], A. Bayly[1]
[1]University of Leeds, United Kingdom

Single droplet drying (SDD) is an established experimental set up in which an isolated droplet is dried under a controlled environment. The drying behavior in the SDD experiments is often complicated and challenged to observe. Hence, a robust model of single droplet drying can provide an ... Read More

Predicting the Fate of Contaminant and Remediating Nano-Particles in a Polluted Aquifer with an Integrated Modeling Approach

S. Nilabh[1], F. Grandia[1]
[1]Amphos 21 Consulting S.L., Spain

The presence of anthropogenic or natural pollutants in groundwater system poses a threat to water resources. Several remediation techniques have been explored and developed to decrease the concentration of contaminants. One such remediation technique, injection of nano-particles in the ... Read More

Simulation of Moisture Ingression in Microelectronics Packages to Correlate Test and Field Conditions

S. Sala[1], L. Zullino[1], R. Cattaneo[1], S. Morin[1], L. Cecchetto[1], A. Andreini[1], M. Rovitto[1], A. Mancaleoni[1]
[1]STMicroelectronics, Italy

Plastic packages, coated with Epoxy Molding Compound (EMC) can provide an economic and versatile protection to the integrated circuits (IC) from mechanical damage. A major drawback of molded packages is that they are not hermetic and are prone to absorb moisture from external ... Read More

Hydromechanical Model of Geological Carbon Sequestration in Saline Aquifers

J. Torres[1], I. Bogdanov[1], M. Boisson[2]
[1]UPPA/CHLOE, France
[2]Total SA, France

Geological Carbon Storage (GCS) is viewed as a viable option to reduce Carbon Dioxide (CO2) emissions. In particular, CO2 injection into deep saline formations (DSF) has been the subject of numerous investigations during the last decade, including pilot and demonstration projects [Reiner ...

Numerical Simulation of The Time-Dependent Permeation Through Barrier Structures

O. Miesbauer[1], J. Tang[1]
[1]Technical University of Munich, Germany

Flexible electronic devices are very sensitive against the ingress of oxygen and water vapor from the atmosphere and therefore have to be protected by encapsulation with high barrier films. Such films contain several polymeric or inorganic layers which are deposited from the liquid or ... Read More

Hydrodynamic Heat Transport Model for Semiconductors with Complex Geometries Including Interfaces

A. Beardo Ricol[1], F. Alvarez Calafell[2]
[1]Universitat Autonoma de Barcelona (UAB), Spain
[2]Universitat Autonoma de Barcelona, Spain

The development of new experimental techniques designed to measure the thermal response of semiconductors at reduced length and time scales is revealing the requirement of generalized heat transport models beyond the classical Fourier law [1,2]. We present the Kinetic Collective ... Read More
