Monte Carlo ion simulation based on neoclassical radial current balance in a divertor tokamak gives a stationary sheared E-->xB--> flow. The neoclassical radial electric field E(r) shows no bifurcation in contrast with earlier orbit loss models, but the shear in E(r) reaches values at which a transition to enhanced confinement has been observed. Also, MHD turbulence analysis shows that a smooth...
quebracho tannin wood adhesive in non formaldehyde approach has low autocondensation rate and needs more press time than formaldehyde-based wood adhesives to produce wood composites. in this study, boric acid was used to increase autocondensation rate of quebracho tannin adhesive to make poplar plywood. the main ingredients of the adhesives include quebracho tannin, naoh, hexamine, boric acid a...
effects of hall current, ion-slip and coriolis force on unsteady mhd couette-hartmann flow of a viscous incompressible electrically conducting fluid through a porous medium bounded by porous plates in the presence of a uniform transverse magnetic field which is either fixed relative to the fluid or to the moving porous plate is investigated using laplace transform technique. the expressions for...
Observations from wave basin experiments and wave-resolving numerical simulations demonstrate the effect of wave-current interaction on shear stress around a sandy mound. show that mound deformation rate morphological patterns depend mixture waves currents in incident flow conditions. A SWASH nonhydrostatic model was used to expand parameter space conditions observed flume characterize response...
