Determining the minimum mass and cost of a magnetic refrigerator
R. Bjørk, A. Smith, C. R. H. Bahl +1
An expression is determined for the mass of the magnet and magnetocaloric material needed for a magnetic refrigerator and these are determined using numerical modeling for both par…
Comparison of adjustable permanent magnetic field sources
R. Bjørk, C. R. H. Bahl, A. Smith +1
A permanent magnet assembly in which the flux density can be altered by a mechanical operation is often significantly smaller than comparable electromagnets and also requires no el…
An optimized magnet for magnetic refrigeration
R. Bjørk, C. R. H. Bahl, A. Smith +2
A magnet designed for use in a magnetic refrigeration device is presented. The magnet is designed by applying two general schemes for improving a magnet design to a concentric Halb…
The sintering behavior of close packed spheres
R. Bjørk, V. Tikare, H. L. Frandsen +1
The sintering behavior of close packed spheres is investigated using a numerical model. The investigated systems are the body centered cubic (BCC), face centered cubic (FCC) and he…
Analysis of the internal heat losses in a thermoelectric generator
R. Bjørk, D. V. Christensen, D. Eriksen +1
A 3D thermoelectric numerical model is used to investigate different internal heat loss mechanisms for a thermoelectric generator with bismuth telluride p- and n-legs. The model co…
In situ characterization of delamination and crack growth of a CGO-LSM multi-layer ceramic sample investigated by X-ray tomographic microscopy
R. Bjørk, V. Esposito, E. M. Lauridsen +5
The densification, delamination and crack growth behavior in a CeGdO (CGO) and (LaSrMnO (LSM) multi-layer ceramic sample was…
