Micromixing devices often utilize complex architectures to mix miscible liquid streams and can be expensive fabricate. Here, we developed, built, experimentally tested, computationally analyzed a serpentine micromixer that fabricated using simple tools supplies available in non-microdevice dedicated laboratories. Fluorescence imaging was used quantify its mixing effectiveness experimentally. A ...

Transmission loss measurements are reported for long steel pipes of circular crosssection, with air inside and out, excited by internal sound. At low frequencies (wavelength greater than the pipe diameter), most of the radiated sound is accounted for by pipe bending waves. In order to approach the much higher transmission loss predicted for pure breathing motion of the pipe, bending waves must ...

The present study deals with the fundamentals of vortex evolution and merging across a 180° sharp bend for laminar inflow (Re = 800). A three-dimensional flow pressure distribution are analyzed by using particle image velocimetry measurements. results show that sudden redirection adverse gradient create recirculation region in vicinity divider wall. vorticity turbulent kinetic energy highlight ...

Flow characteristics in a model of a stationary two-pass internal coolant passage were measured with the stereoscopic PIV technique. From the PIV measurements, the 3D mean velocity field and turbulence quantities of the flow were obtained simultaneously with high spatial resolution, which allowed for an understanding of the flow phenomena in the coolant passage. The model of the coolant passage...

Different flow-altering methods, such as W−Weirs, have been developed to reduce erosion. For this study, we performed two experiments: (1) installing a W−Weir in various positions determine the best angle for placement, and (2) investigating variation of flow patterns bed shear stress distribution 90-degree sharp bend by measuring 3D components velocities, with without where greatest scour dept...

You who more than oncespelled angle when meaning angel,are now one—maybe both.A sharp line on white paperdriving hardand fastin another spacewhose numbersI do not know.YetIn the arithmeticof our individual journeys,let us incline,My dearest angle,toward that vertexthat despite variantswe bend,infinite together,while angels math.
