Vortex Line Density in a Superfluid Turbulent Wake in the Zero Temperature Limit

open access: yesAnnalen der Physik, EarlyView.
The quasiclassical conjecture for quantum turbulence in a pure superfluid straightforwardly leads to the definition of the superfluid Reynolds number, Res=ud/κ$Re_s=ud/\kappa$, and suggests that the effective quantum viscosity should be of the order of the circulation quantum κ$\kappa$.

Characteristics of Enhanced Heat Transfer of Nanofluid in Microchannels Under Electric and Magnetic Co‐Excitation

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Due to its small size, microchannel heat exchangers are widely used in fine engineering fields such as electronic equipment. In this paper, the boiling heat transfer characteristics of refrigerants and nanofluids in microchannels are studied by applying electric fields, magnetic fields, and electromagnetic synergistic fields.

Buoyancy‐Driven Micropolar Fluid Flow Transport in Porous Media With Variable Heat Source and Convective Heating

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The objective of the current research is to characterize the thermal performance in micropolar fluid flows on a vertically elongated porous sheet in the presence of buoyancy forces. Thus, the motivation of this study is to improve the understanding of buoyancy‐driven micropolar fluid flows through porous media, which are relevant to advanced ...

Numerical Analysis of Proton Exchange Membrane Fuel Cell Performance With a Lung Serpentine Flow Field

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Proton exchange membrane fuel cells (PEMFC) are regarded as the best clean energy conversion technology because of their smaller number of emissions and higher efficiency. This numerical investigation used two different flow channel designs—the serpentine flow field (SFF) and the lung serpentine flow field (LSFF)—with active areas of 5 by 5 cm.
