The Effect of Composition on the Role of Evaporation During Oil Recovery by Combustion

N. Khoshnevis Gargar[1], A. Mailybaev[2], D. Marchesin[2], H. Bruining[1]
[1] Delft University of Technology, Delft, The Netherlands
[2] Instituto Nacional de Matematica Pura e Aplicada, Rio de Janeiro, Brazil

One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. The ... Read More

High Curvature Bending of Ultra-Thin Chips and Chip-on-Foil Assemblies

D. van den Ende[1]
[1]Holst Centre / TNO, Eindhoven, The Netherlands

Ultra-thin chips of less than 20µm become flexible, allowing integration of silicon IC technology with highly flexible electronics. This combination allows for highly intelligent products of unprecedented thinness, flexibility and cost. Examples include sensor systems integrated into ... Read More

Simulation of Thermal Transport Based Flow Meter for Microfluidics Applications

E. Byas[1], A. Arevalo[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

COMSOL Multiphysics® is used to simulate a thermal transport based flow sensor, which will be embedded in a micro-channel of a Poly-methyl methacrylate (PMMA) based microfluidic device. The channel height is 100μm and for simulation purposes the lengths has been set to 1.2mm. The heater ... Read More

Thermal Integration of Coupled SOFC System with a High-Performing Metal Hydride Storage

A. Mossadegh Pour[1], A. Dhira [1], R. Steinberger-Wilckensa[1]
[1]Department of Chemistry, University of Birmingham, Edgbaston, Birmingham, United Kingdom

Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs ... Read More
