Transport Phenomena at High Mass Flux

Mass Transport Phenomena in a MCFC Cathode

A molten carbonate fuel cell (MCFC) is an electro-chemical energy conversion technology that runs on natural gas and employs a molten salt electrolyte. In order to keep the electrolyte in this state, the cell must be kept at a temperature above 500◦C, eliminating the need for precious metals as the catalyst. There has been only a limited amount of research on modelling the transport processes i...

High pT Phenomena at RHIC

First data from RHIC reveals a suppression of hadron production at high pT in central Au-Au collisions relative to the expectation from nucleonnucleon collisions. Known nuclear effects are excluded as origin. The apparent suppression of high pT hadrons thus indicates quenching of jet production. The origin of this jet quenching is uncertain and whether it is related to parton energy loss throug...

Magnetic Flux Transport at the Solar Surface

After emerging to the solar surface, the Sun’s magnetic field displays a complex and intricate evolution. The evolution of the surface field is important for several reasons. One is that the surface field, and its dynamics, sets the boundary condition for the coronal and heliospheric magnetic fields. Another is that the surface evolution gives us insight into the dynamo process. In particular, ...

Magnetically collimated jets with high mass flux

Recent numerical simulations and analytical models of magnetically collimated plasma outflows from a uniformly rotating central gravitating object and/or a Keplerian accretion disk have shown that relatively low mass and magnetic fluxes reside in the produced jet. Observations however indicate that in some cases, as in jets of YSO’s, the collimated outflow carries higher fluxes than these simul...
