Flow boiling in microchannels is one of the most desirable cooling solutions for high power electronics. However, it challenging to promote flow performance, particularly critical heat flux (CHF), due their unfavorable liquid rewetting. Inlet restrictors (IRs) have been successfully used manage two-phase instabilities microchannels. IRs would result extremely pressure drop. In this study, witho...

Using a second order turbulent closure, the turbulent flow over a wavy bottom is derived as a systematic expansion with respect to the amplitude of the corrugation. The article is focused on the analysis of the dynamical mechanisms controlling the different regions of the flow. It aims also at calculating the shear and normal stresses applied to the ground, which constitute key ingredients of t...

The present comprehensive physical and optical measurements have captured sediment resuspension associated with two hurricanes, Edouard and Hortense, that passed over the Coastal Mixing and Optics study site in the fall of 1996. Sediment resuspension associated with Hurricane Edouard was forced by combined current and wave processes. Combined current-wave bottom shear stresses exceeded 3.5 dyn ...

Automatic stress prediction is helpful for both speech synthesis and natural speech understanding. This paper proposes a novel hierarchical Mandarin stress modeling method. The top level emphasizes stressed syllables, while the bottom level focuses on unstressed syllables for the first time due to its importance in both naturalness and expressiveness of synthetic speech. Maximum Entropy model i...

A series of dye releases in the Hudson River estuary elucidated diapycnal mixing rates and temporal variability over tidal and fortnightly time scales. Dye was injected in the bottom boundary layer for each of four releases during different phases of the tide and of the spring–neap cycle. Diapycnal mixing occurs primarily through entrainment that is driven by shear production in the bottom boun...
