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...

Analysis of the diffuse-domain method for solving PDEs in complex geometries

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1242503

In recent work, Li et al. [Commun. Math. Sci., 7, 81-107, 2009] developed a diffusedomain method (DDM) for solving partial differential equations in complex, dynamic geometries with Dirichlet, Neumann, and Robin boundary conditions. The diffuse-domain method uses an implicit representation of the ge...

CO2 Capture from Off-shore Gas Turbines Using Supersonic Gas Separation ☆

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1190264

CO2 capture from gas turbine based off-shore application face challenges such as size (foot-print), weight and stability (wave motion) in addition to the challenges faced by on-shore industry. Space- and weight challenges are given priority, and the size of the capture installations will be of impor...

A robust method for calculating interface curvature and normal vectors using an extracted local level set

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1059203

The level-set method is a popular interface tracking method in two-phase flow simulations. An often-cited reason for using it is that the method naturally handles topological changes in the interface, e.g. merging drops, due to the implicit formulation. It is also said that the interface curvature a...
