Thermodynamic modeling with equations of state: present challenges with established methods

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1457656

Equations of state (EoS) are essential in the modeling of a wide range of industrial and natural processes. Desired qualities of EoS are accuracy, consistency, computational speed, robustness and predictive ability outside of the domain where they have been fitted. In this work, we review present ch...

Avoiding Damage of CO2 Injection Wells Caused by Temperature Variations

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1487346

Well integrity is a prerequisite for safe geological storage of CO2. Both active and abandoned wells are man-made channels between the storage reservoir and the atmosphere that can become leakage paths over time. The CO2 injection wells are of special concern, as they are exposed to low temperatures...

Study of Thermal Variations in Wells During Carbon Dioxide Injection

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1356624

Carbon dioxide (CO2) can be injected into the subsurface for the purpose of enhanced oil recovery (EOR), possibly with geological CO2 storage. This procedure brings about a set of unique challenges with respect to well construction, operation and remediation. As compared to normal production, CO2 in...

A large time step Roe scheme applied to two-phase flow

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1361863

We consider a large time step (LTS) Roe scheme, originally suggested by LeVeque [Comm. Pure Appl. Math., 37 (1984), pp. 463-477] which has attained increased popularity in recent years. The scheme is based on a wave formulation of the ordinary Roe scheme, and the assumption that waves interact linea...

Potential of enhancing a natural convection loop with a thermomagnetically pumped ferrofluid

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1358679

The feasibility of using a thermomagnetically pumped ferrofluid to enhance the performance of a natural convection cooling loop is investigated. First, a simplified analytical estimate for the thermomagnetic pumping action is derived, and then design rules for optimal solenoid and ferrofluid are pre...

A Two-Fluid Model for Vertical Flow Applied to CO2 Injection Wells

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1361080

Flow of CO2 in wells is associated with substantial variations in thermophysical properties downhole, due to the coupled transient processes involved: complex flow patterns, density changes, phase transitions, and heat transfer to and from surroundings. Large temperature variations can lead to therm...
