Dissipation flux pinning

Understanding flux motions and especially identifying the mechanism(s) for pinning at present remain a challenging opportunity. Measurements of a dissipation peak at near 45 K (well below Tc) in Bi-Sr-Ca-Cu-O samples oscillating in a magnetic field and interpreted... 

Peles et al. [22] investigated heat transfer and pressure drop phenomena over a bank of micro-pin fins in a micro-heat sink. The dimensionless total thermal resistance was expressed as a function of Re)molds number, Prandtl number and the geometrical configuration of the pin-fin microheat sink. They compared their theoretical model with their experimental results and concluded that very high heat fluxes can be dissipated at a low wall terr5>erature rise using a microscale pin-fin heat sink. Thus, forced convection over shrouded pin-fin arrays is a very effective cooling device. In many cases, the primary cause for the rise in wall temperature is the increase of the fluid tempera-...
