The ability to manipulate supported lipid bilayers after formation on a substrate has made possible new classes of both molecular and cellular level experiments. In this report, we combine the unique ...
Flow past a single rotating cylinder has been studied, both numerically and experimen tally, by many authors. In contrast is the flow past rotating cylinders in a side-by-side arrangement, which...
This paper reports development of a two-dimensional solver for compressible viscous flow using spectral difference (SD) method and its applications on simulating laminar flow past two side...
The computation of boundary layer properties and laminar-to-turbulent transition location is a very complex problem, generally not undertaken in the context of aircraft design. Yet if an aircraft i...
e numerically investigate the underlying physics of two peculiar phenomena, which are axis-switching and saddle-back velocity profile, in both laminar and turbulent rectangular jets using lattice Bolt...
Algal swimming is often biased by environmental cues, e.g. gravitational and viscous torques drive cells towards downwelling fluid (gyrotaxis). In view of biotechnological applications, it is importan...
We study two-phase stratified flow where the bottom layer is a thin laminar liquid and the upper layer is a fully-developed gas flow. The gas flow can be laminar or turbulent. To determine the boundar...
针对国家同步辐射实验室燃烧与火焰实验站中1 m Seya-Namioka 单色仪对光栅的需求,采用全息离子束刻蚀工艺制作了1 200 lp/mm Laminar光栅。首先,通过光刻胶灰化技术调节光刻胶光栅掩模占空比,在理论设计的误差允许范围内,对此光栅掩模进行扫描离子束刻蚀;然后,将光栅图形转移到光栅基底中去除残余光刻胶;最后,采用离子束溅射法镀制厚约40 nm的金反射膜,采用热蒸发法镀制厚约60...
为了确定生物质热分解产物在层流炉内的停留时间,设计了一套层流炉透明冷态模拟装置,以炭粉代替生物质热解固体产物,利用PIV技术测量炭粉在不同主气流量和收集距离下的停留时间。根据流场相似准则,即冷态流场与热态流场雷诺数相等,确定主气流量分别为1.0、1.5、2.0和2.5m3/h;收集距离由热态实验确定,分别为200、250、300和350mm。测量结果表明:对于同一收集距离,炭粉的实际停留时间与...
We have developed a capillary chromatography system using an open capillary tube made of fused-silica, polyethylene, or poly(tetrafluoroethylene), and a water–hydrophilic–hydrophobic organic mixture c...
In this study, laminar flow and heat transfer in a circular pipe with an inner tube inserted was investigated numerically. For this reason, two-dimensional Navier-Stokes, continuity and energy equatio...
Free convection heat transfer has been experimentally investigated for laminar air flow in a vertical circular pipe by using the boundary condition of constant wall heat flux in the ranges of RaL from...
Fully developed laminar mixed convection has been investigated numerically in a vertical double-passage channel by taking into account the effect of viscous dissipation. The channel is divided into tw...
Starting from the Navier-Stokes and the continuity equations of a viscous incompressible fluid, a statistical theory is developed for the prediction of transition and break down to turbulence in a lam...
Starting from the basic conservation laws of fluid flow, we investigated transition and breakdown to turbulence of a laminar flat plate boundary layer exposed to small, statistically stationary, two-c...
