Our long-term goals are to develop a physical understanding of the processes which lead to mixing in the ocean, with the aim of using this understanding to develop parameterizations of mixing suitable for global and regional models, and applying such models to societally relevant problems. A particular focus is the mixing induced by tidal flow over topography, and mixing induced by breaking non...

Surface waves play an essential role in regulating the mixing processes upper ocean boundary, and then directly affect air–sea exchange of mass energy, which is important for intensity prediction tropical cyclones (TCs). The relative integrated impacts wave breaking (WB) orbital motion (WOM) on response to TC forcing are investigated under typhoon Megi (2010), using modeled data from a fully co...

Very-high-frequency surface acoustic waves, generated and transmitted along singlecrystal lithium niobate, are used to drive homogeneous aqueous suspensions of polystyrene nanoparticles along microchannels. At a few hundred milliwatts, uniform and mixing flows with speeds of up to 10mm/s were obtained in centimetres-long rectangular channels with crosssectional dimensions of tens to a few hundr...

Xu2 1 Department of Mechanical Engineering The Hong Kong Polytechnic University, Hong Kong 2 Department of Physics Zhejiang Normal University, Jinhua 321004, CHINA Abstract Mixing of analytes and reagents in microfluidic devices is often crucial to the effective functioning of lab-on-a-chip. It is possible to affect the mixing in microfluidics by intelligently cont...

Simulated mixing rates of the Rayleigh-Taylor instability for miscible fluids with physical mass diffusion are shown to agree with experiment; for immiscible fluids with physical values of surface tension the numerical data lie in the center of the range of experimental values. The simulations are based on an improved front tracking algorithm to control numerical surface tension and on improved...

For implementation of the free surface boundary condition, a new subroutine has been introduced to an existing steady 3-D body fitted code. This code was previously written for steady flow simulation in closed ducts. The algorithm used in this subroutine reduces the instability problem according to the free surface wave generation. For code validation, it was applied to two different open cha...

We have computed new solar models using the same stellar evolution code as described in Charbonnel, Vauclair and Zahn (1992). This code, originating from Geneva, now includes the computation of element segregation for helium and 12 heavier isotopes. It may also include any type of mixing of the stellar gas, provided this mixing may be parametrized with an effective diffusion coefficient as a fu...

In this study, we incorporated mixing units of three-dimensional (3D) interconnected pore network inside microfluidic channels by combining single prism holographic lithography and photolithography. 3D pore network structures were generated by the interference of four laser beams generated by a truncated triangular pyramidal prism. The levelling between the 3D porous structures and the channel ...

A tropical cyclone (TC) usually induces strong sea-surface cooling due to vertical mixing. In turn, surface influences the intensities and tracks of TCs. Therefore, relationship between temperature (SST) TC is one important components air-sea interaction. Sea-surface associated with three TCs (Bailu, Lingling, Mitag) was investigated based on wave-glider observations, satellite altimetry, Massa...
