Radial motion of highly conducting sphere in magnetic field
Gurcan, OD; Mirnov, VV; Ucer, D (2000-05-01)
Radial motion of a highly conducting sphere in external magnetic field is considered. It both perturbs the external magnetic field and generates an electric field. Exact analytic solution has been obtained previously for a uniformly expanding sphere. In the present paper a new exact solution is derived which is valid not only for expansion but for contraction as well. It allows us to calculate analytically the total electromagnetic energy irradiated by the sphere involved in periodical radial motion with ar...
Radial basis function and dual reciprocity boundary element solutions of fluid dynamics problems
Gürbüz, Merve; Tezer Sezgin, Münevver; Department of Mathematics (2017)
In this thesis, the two-dimensional, laminar steady or unsteady flow of a viscous, incompressible, electrically conducting fluid is considered in channels of several geometries under the impact of a uniform magnetic field with different orientations. Magnetohydrodynamic (MHD) flow governed by the hydrodynamic and electromagnetic equations is solved numerically with or without Stokes approximation and with or without magnetic induction due to the large or small values of Reynolds and magnetic Reynolds number...
Radial distribution of local concentration weighted particle velocities in high density circulating fluidized beds
Külah, Görkem; Bi, X; Lim, J; Grace, J R (null; 2007-05-01)
An extensive experimental investigation of radial profiles of concentration -weighted particle velocities was carried out by simultaneously measuring local transient particle velocity, solids concentration and solids flux using a three-fibre optical probe at five axial levels and seven radial locations in a 0.2 m diameter riser operating over a wide range of solids circulation fluxes (198 to 350 kg/m 2s) and superficial gas velocities (6 to 8 m/s). Particle velocities averaged over time and concentration-we...
Radial excitations of the decuplet baryons
Alıyev, Tahmasıb; Sundu Pamuk, Hayriye (2017-04-10)
The ground and first excited states of the decuplet baryons are studied using the two-point QCD sum rule approach. The mass and residue of these states are computed and compared with the existing experimental data and other theoretical predictions. The results for the masses of the ground state particles as well as the excited Delta and Sigma* states are in good consistency with experimental data. Our results on the excited Xi* and Omega(-) states reveal that the experimentally poorly known Xi(1950) and Ome...
Radial junction solar cells prepared on crystalline si by metal assisted electroless etching
Baytemir, Gülsen; Es, Fırat; Turan, Raşit (null; 2016-06-05)
Radial junction solar cell has been proposed as an alternative device geometry to conventional planar solar cells with its remarkable electrical and optical performance. In this geometry, micro/nano pillars on the surface allow minority carrier collection in the radial direction and shorten the carrier diffusion length. Moreover, increased light trapping in the pillars and reduced reflection from surface enhance the solar cell efficiency. In their letter (article no. 1600444) Baytemir et al. have investigat...
