Abstract: Abstract This paper compares the optimal geometry of a rectangular microchannel heat sink (MCHS) for different channel wall surfaces, namely, conventional (uncoated and smooth), hydrophobic, and superhydrophobic. For this purpose, the three-dimensional Navier-Stokes and energy… read more here.

DOI: 10.1016/j.ijnonlinmec.2018.11.001
Abstract: Abstract In operation, blisks are subject to dynamic loading, which result in large response amplitudes near resonance. To reduce the response level and prevent damages caused by high cycle fatigue, friction damping sources are introduced… read more here.
