Investigating the effect of magnetic field on the slip flow behavior of air-fluid in a rectangular microchannel by Mohsen Saghafian, Mehdi Moslehi, Omid Ali Akbari

“…In this study, the space between the slider and the hard disk is simulated as a two-dimensional microchannel with specific boundary conditions affected by the magnetic field. In a microchannel with asymmetric wall heating, uniform heat flux, and influenced by a uniform magnetic field, the study numerically investigates laminar flow and forced convection heat transfer of a Newtonian fluid. …”

Wavelet and Network Analysis of Magnetic Field Variation and Geomagnetically Induced Currents During Large Storms by L. Orr, S. C. Chapman, C. D. Beggan

“…Coherent response is excited across spatially extended clusters comprised of a subset of nodes that are highly connected to each other, with a tendency for east‐west linkages following that of the physical grid, simultaneous with the overhead presence of the auroral electrojet and the inducing component of the magnetic field. This can quantify the spatial and temporal location of increased hazard in specific regions during large storms by including effects of both the geophysical and engineering configuration of the high voltage grid.…”
