The present analysis focuses on the investigation of two-dimensional flow passing a bridge pier nearby splitter plate in different regimes laminar flow. is T-shaped and two cases have been studied based form relative to pier. implemented for steady incompressible water an open channel. current study deals with velocity vectors, drag coefficients, lift skin friction. vector gave good indicator a...

Modeling of turbulent flows remains a very challenging unsolved problem. Based on symmetries the fluid equations we propose closure expressing Reynolds stress as quadratic nonlocal functional time averaged velocity field only, contrary to RANS models based upon algebraic handling which lead complex nonlinear partial differential equations. We test our model mixing layer behind splitter plate in...

In this article, we suggested a novel design of polarization splitter based on coupler waveguide on InP substrate at 1.55mm wavelength. Photonic crystal structure is consisted of two dimensional (2D) air holes embedded in InP/InGaAsP material with an effective refractive index of 3.2634 which is arranged in a hexagonal lattice. The photonic band gap (PBG) of this structure is determined using t...

We present a simple motorized rotation mount for half-wave plate that can be used to rapidly change the polarization of light. use device switch high power laser beam between different optical dipole traps in an ultracold atom experiment. The uses stepper motor with hollow shaft, which allows propagate along axis minimizing inertia and mechanical complexity. A machined adapter is wave plate. ch...

The transverse flow-induced vibration (FIV) of an elastically-supported cylinder-plate assembly (viz., a rigid splitter-plate attached to the downstream side circular cylinder) with low mass ratio 10 and zero structural damping is investigated using numerical simulations at Reynolds number 100. oscillations characteristics flow around structure are analyzed in terms fluid forces as function pla...
