Monte-Carlo Model for Radiation Transport in Solid X-Ray Targets

Christian Feist¹, Arno Plankensteiner²
¹CENUMERICS, Haspingerstrasse 16, 6020 Innsbruck, Austria
²PLANSEE SE, Metallwerk-Plansee-Strasse 71, 6600 Reutte, Austria

X-rays represent high-energy electromagnetic radiation capable to penetrate matter and are therefore widely used in medical diagnostics, material testing and various other applications. They are typically produced by vacuum tubes with electrons emitted from a hot cathode and accelerated ... En savoir plus

Oxygen Based Diffusion Modeling of Oxidation Behaviour of Encapsulated Lipids

H. Teichmann [1], A. Linke [1], R. Kohlus [1],
[1] Process Engineering and Food Powders, University of Hohenheim, Stuttgart, BW, Germany

Encapsulation is an established technique to protect sensitive materials from environmental factors such as oxygen and light. Nutritionally beneficial fatty acids like omega 3 fatty acids are susceptible to oxidation and are therefore encapsulated by drying an oil in water emulsion. It ... En savoir plus

Study of 3D Focused Droplet Generation in a 2D Flow Focusing Microfluidic Geometry

A. Mohan [1], P. Gupta [2], T. Saiyed [2], Dr. A. Prabhakar [1],
[1] Indian Institute of Technology Madras, Chennai, Tamil Nadu, India
[2] Centre for Cellular and Molecular Platforms, Bangalore, Karnataka, India

We have chosen droplet-based microfluidics as a platform for single cell analysis using the encapsulation technique. For this, we study the water in oil droplets formation inside a 2D microfluidic flow focusing geometry designed. We have performed Computational Fluid Dynamics (CFD) ... En savoir plus

Transport, Growth, Decay and Sorption of Microorganisms and Nutrients through Porous Media: A Simulation with COMSOL

D. Lopez-Falcon, M. Diaz-Viera, and A. Ortiz-Tapia
Instituto Mexicano del Petroleo, México D.F., Mexico

Transport of microorganisms through porous media governs many phenomena in bioremediation of environmental pollution problems and microbial enhanced oil recovery. The aim of this work is to investigate the effects of some transport parameters on breakthrough curves as well as on spatial ... En savoir plus

Pore-Level Bénard–Marangoni Convection in Microgravity

P. Mohammadmoradi [1], A. Kantzas [1],
[1] University of Calgary, Calgary, AB, Canada

Pore-level displacement of heavy-oil during thermal operations such as SAGD and CSS is a complex multi-scale phenomenon. As gravity drainage is the main depletion mechanism within the intergranular pore space, the surface tension-related phenomena are dominant in intra-granular micro ... En savoir plus

Modeling and Simulation Study of a Fixed-Bed Catalytic Reactor for the Hydrogenation of CO2 to CH4

Iñigo Lacarra Etxarri¹, Elena Gómez Bravo¹, Beñat Pereda Ayo¹, José Antonio González Marcos¹, Juan Ramón González Velasco¹
¹University of the Basque Country

The "Power to Gas" technology is a promising alternative for storing renewable electrical energy through energy carriers. This technology involves using surplus energy from renewable sources to obtain green hydrogen through water electrolysis. Since hydrogen storage and transportation ... En savoir plus

Numerical Modeling of Solvent Enhanced Water Flooding

M. Chahardowli [1], R. Farajzadeh [2], H. Bruining [1],
[1] Delft University of Technology, Delft, The Netherlands
[2] Shell Global International Solutions, Den Haag, The Netherlands

Mutually soluble-solvents can improve the ultimate recovery in conventional reservoirs. Initially, the solvent moves with the imbibing aqueous phase into the reservoir. However, upon contact with oil, diffusion occurs and the solvent is transported in the oleic phase. Through the ... En savoir plus

Numerical Investigation of Micro Droplet Contact Angle Hysteresis on a Heterogeneous Solid Surface: Application to Carbonate

M. Zaidani[1], M. Sassi[1]
[1]Khalifa University of Science and Technology, United Arab Emirates

Contact angle hysteresis is an important physical phenomenon, it is an essential parameter in wetting and capillarity, and it plays an important role in many industrial processes, especially in Enhanced Oil recovery (EOR). In this paper, the contact angle hysteresis (CAH) of ... En savoir plus
