Pump sump design is very crucial in ensuring a minimum requirement for its operation. Improper pump will influence the development of vortices and swirls that can adversely affect efficiency which subsequently could damage pump. This be mitigated by installing an anti-vortex device (AVD) beneath intake pipe sump. The AVD works suppressing flow water into pipe. ANSI/HI 9.8-2012 standard has outl...

We study experimentally the atomization of a liquid sheet by a parallel gas flow, in order to understand the conditions of destabilization of the liquid sheet and the conditions of drop creation. We study in particular the regimes at low M (ratio of gas/liquid dynamic pressures), to test the scaling law proposed and validated in previous studies at large M(M = 16). The inviscid stability analys...

The problem of generation self-sustained oscillations in the flow past a circular cylinder with splitter plate is solved numerically. We investigate both transient process and steady periodic vortex shedding behind cylinder. evolution vorticity field shown for various length plate. It demonstrated that oriented along direction significantly reduces forces applied to With increasing average drag...

The effect of base suction on a plane wake was found to produce significant changes on wake dynamics. The wake is produced by merging two boundary layers from the trailing edge of a splitter plate in a two stream water tunnel. A threshold suction speed exists which is equal to half of the free stream velocity. If the suction speed is below the threshold, the wake flow is unstable. If the suctio...

In this paper, we numerically simulated a glass-based all-optical 1×N power splitter with eleven different configurations using soliton breakup in a nonlinear medium. It is shown that in addition to reconfigurability of the proposed splitter, its power splitting ratio is tunable up to some extent values too. Nonlinear semivectorial iterative finite difference beam propagation method (IFD-...

designing a power splitter with five ports has been shown in this article. in order to prevent the direct coupling between waveguides, a t-shaped structure with an appropriate distance has been used. the coupling between the parallel photonic crystal waveguides is based on multimode interference, while selecting the output efficiency is performed by setting the refractive coefficients and radiu...

This paper describes the passive flow control of fluid in the downstream direction of the circular tube and in tube banks by means of splitter plate. Heat transfer and pressure drop depend on complex flow pattern of fluid in tube banks, whereas pressure drop linked directly with the fluid pumping capacity. A primary focus is to review experimental, analytical and numerical works that had been c...

We describe a polarization Sagnac interferometer with an in-loop half-wave plate that allows signal detection at the reciprocal port of the beam splitter while maintaining the ability to detect the signal at a dark fringe. Postmodulation and balanced heterodyne detection are used to recover the signal. This topology is simple to control because of its common-path characteristics and its colline...
