We analyze the incompressible flow past a square cylinder immersed in wake of an upstream splitter plate, which separates two streams different velocities, U T (top) and B (bottom). The Reynolds number associated with below plate is kept constant at [Formula: see text], based on side D as characteristic length. top-to-bottom dissymmetry measured by ratio text] between numbers above plate. equiv...

here, we propose an optical filter and an optical power splitter based on two-dimensionalphotonic crystal all circular ring resonators. these structures are made of a square lattice ofsilicon rods with the refractive index n1=3.464 surrounded by air (with refractive indexn2=1). first, we have designed the filter and by using that, we designed a power splitter. thetransmission efficiency and qua...

We consider the problem of an atomic beam propagating quantum mechanically through an atom beam splitter. Casting the problem in an adiabatic representation (in the spirit of the Born-Oppenheimer approximation in molecular physics) sheds light on explicit effects due to nonadiabatic passage of the atoms through the splitter region. We are thus able to probe the fully three-dimensional structure...

An alternate renewable energy source, through a piezoelectric vibration harvester with bluff splitter body, could lead to higher efficiency in harvesting, vortex-induced at near-resonance condition 20 m/s high wind speed. However, is not as popular solar energy, the main source Malaysia, due relatively low speed available country. The INVELOX machine, introduced 2014, was one of most recent sys...

In actual engineering, asymmetric flow often occurs, but rigid partitions are installed in the direction of field and symmetric direction. This will result a deflection angle between dividing plate incoming flow. The research results show that when declination is low, partition has limited impact on system; about 10 degrees, system vibration characteristics have abrupt changes, amplitude decrea...

A quantum system can behave as a wave or as a particle, depending on the experimental arrangement. When, for example, measuring a photon using a Mach-Zehnder interferometer, the photon acts as a wave if the second beam splitter is inserted, but as a particle if this beam splitter is omitted. The decision of whether or not to insert this beam splitter can be made after the photon has entered the...

The flow field in a centrifugal fan is highly complex with flow reversal taking place on the suction side of impeller and diffuser vanes. Generally performance of the centrifugal fan could be enhanced by judiciously introducing splitter vanes so as to improve the diffusion process. An extensive numerical whole field analysis on the effect of splitter vanes placed in discrete regions of suspecte...
