While adaptive optical systems are able to remove moderate wavefront distortions in scintillated optical beams, phase singularities that appear in strongly scintillated beams can severely degrade the performance of such an adaptive optical system. Therefore the detection of these phase singularities is an important aspect of strong-scintillation adaptive optics. We investigate the detection of ...

Abstract An unsteady flow and heat transmission of ionized gases via a horizontal channel enclosed by non-conducting plates in rotating framework with Hall currents is examined using electro-magnetohydrodynamic (EMHD) two-fluid flow. The current impact taken into account assuming that the are totally ionized, applied transverse magnetic field very strong. For temperature velocity distributions ...

The phenomena of magneto-hydrodynamic natural convection in a two-dimensional semicircular top enclosure with triangular obstacle the rectangular cavity were studied numerically. governing differential equations are solved by using most important method which is finite element (weighted-residual method). wall placed at cold Tc and bottom heated Th. Here sidewalls assumed adiabatic. Also all occ...

A numerical investigation has been executed in a curve-shaped enclosure crammed with hybrid nanofluid containing wavy-shaped inner cylinder the existence of magnetic field. mixture copper and alumina nanoparticles normal water-based solution is used to create nanofluid. The natural convective flow generated as result temperature difference between cold outer hot wavy cylinder. parametric examin...

Pumping fluid is one of the crucial parts any microfluidic system. Using electric and magnetic fields as a substitute for moving can have many advantages. In this study hydrodynamic heat transfer characteristics electroosmotic flow under influence lateral transverse field, are studied numerically. Results indicate that dimensionless parameters such Hartmann number, intensity pressure gradient p...
