[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 migration of the mutually soluble component from the aqueous phase into the oleic phase, oil properties and/or rock ...

Effect of Area of the Reaction Surface on the Capture Efficiency of Immunosensors

D. Rath [1], S. Panda [1],
[1] Indian Institute of Technology, Kanpur, India

With the progress of immunosensing technology, the detection of diseases at early stages is feasible using surface based heterogeneous immunosensors [1]. Literature contains few reports where it is verified that reaction spot of smaller size leads to high fractional occupancy of targets, specifically applicable to the microarray technology [2]. Such enhancement in capture efficiency by the ...

In an experimental nuclear fusion facility dust is generated both during normal machine operations and by macroscopic erosion of the plasma facing materials due to intense thermal loads. This dust can be mobilized by air ingress in case of LOVA (Loss of Vacuum Accident) threaten safety of workers and public. A small facility, Small Tank for Aerosol Removal and Dust (STARDUST), was set up in ...

Modelling of Melt Cast Cooling and Solidification Processes for Explosives

P. Lamy-Bracq[1] and C. Coulouarn[1]
[1]Nexter Munitions, Tarbes, France

A solidification process of casting explosives in shell is studied in this paper. An enthalpy method approach is used to model the solidification process. Both the thermal and mechanical effects are taken into account. An ALE (Arbitrary Lagrangian-Eulerian) method is used to represent the physical deformation due to solidification. Results from the model are verified against experimental ...

Quench Propagation in 1-D and 2-D Models of High Current Superconductors

G. Volpini[1]
[1]LASA Lab., Milan Dept., Istituto Nazionale di Fisica Nucleare, Milano, Italy

The understanding of quench, or the sudden transition to the normal state of a high-current Superconductor (SC), is fundamental for the design of a SC magnet, and it is widely discussed in the literature. This paper presents some simple COMSOL models, which are compared with well-known approximate formulae and some experimental results. These models allow a more precise description than it is ...

Use of COMSOL as an Educational Tool Through its Application to Ground Water Pollution

Ensuring the quality of underground water and controlling its quantity is of major concern for the population. Therefore, this subject attracts many students from different specialties at different levels of their curriculum. In fact, the pedagogic objectives of the course may be different according to the level or/and interest of the students and COMSOL is used due to its versatility. In this ...

COMSOL Derived Universal Scaling Model For Low Reynolds Number Viscous Flow Through Microfabricated Pillars – Applications to Heat Pipe Technology

Cooling of high-power density electronic devices remains a challenge. Microfluidic heat-pipes with the potential of achieving ultra-high thermal conductivities offer a low-cost technology for cooling electronics. To achieve high thermal conductivity, it is critical to maximize the rate of liquid transport inside the heat pipe. We propose a novel array of microfabricated pillars to maximize ...
