Chilldown process is a complicated process involves unsteady two-phase heat and mass transfer and initiates the cryogenic fluids transport. To advance the understanding of this process, both experimental and modeling investigations have been carried. The chilldown process can be generally divided into three regions which are associated with different flow regimes and heat transfer mechanisms. Under low flow conditions, the two-phase flow durin...

Working memory (WM), which includes short-term memory and cognitive control, has been found to be closely related to a wide range of high-level cognitive abilities and academic achievement. Prior studies showed children with attention-deficit/hyperactivity disorder improved their WM and fluid intelligence through computerized cognitive training (CCT) in a clinical setting. This research examined whether regular middle-school students would sig...

Solid oxide fuel cells (SOFCs) are expected to be widely applicable for both small and large-scale power generation systems. The reason is that the SOFC is simple, highly efficient, tolerant to impurities, and can at least partially internally reform hydrocarbon fuels. A multi-physics, multi-scale model structure is proposed by integrating three submodels, i.e., a macro-continuum model, a micro-scale model (random walk model) and an atomistic-...
