| 1 | Hydromagnetic flow between two porous disks rotating about non-coincident axes显示文摘在与一样的尖速度 Ω
旋转的二个多孔的磁盘之间的 Hydromagnetic 流动大约二非 -- 重合的轴面对一个一致横向的磁场被学习了。管理方程的一个准确答案在一张关上的表格被获得了。主要速度 f/Ωl 增加,第二等的速度 g/Ωl 随任何一个雷纳兹数字 Re 或 Hartman 的增加减少,这被发现数字 M。这也被发现在 0 随 M 2 或 K 2 的增加增加的磁盘 η
= 的转矩。在另一方面在磁盘 η
= 没有转矩 1 为大 M 2 和 K 2 。热转移特征也在拿上被学习了粘滞并且朱尔驱散进说明。温度随 M 2 或 K 2 的增加增加,这被看见。热的率在 0 随 M 或 K 的增加增加的磁盘 η
= 转,这被发现。在另一方面在 1 随 K 的增加增加,但是随 M 的增加减少的磁盘 η
= 的热转移的率。 | M.Guria B.K.Das R.N.Jana C.Erdem Imrak | 2008 | Acta Mechanica Sinica2008，24，5： | 2 |
| 2 | Entropy analysis of unsteady magneto-nanofluid flow past accelerating stretching sheet with convective boundary condition显示文摘The unsteady laminar magnetohydrodynamics(MHD) boundary layer flow and heat transfer of nanofluids over an accelerating convectively heated stretching sheet are numerically studied in the presence of a transverse magnetic field with heat source/sink.The unsteady governing equations are solved by a shooting method with the Runge-KuttaFehlberg scheme. Three different types of water based nanofluids, containing copper,aluminium oxide, and titanium dioxide, are taken into consideration. The effects of the pertinent parameters on the fluid velocity, the temperature, the entropy generation number, the Bejan number, the shear stress, and the heat transfer rate at the sheet surface are graphically and quantitatively discussed in detail. A comparison of the entropy generation due to the heat transfer and the fluid friction is made with the help of the Bejan number.It is observed that the presence of the metallic nanoparticles creates more entropy in the nanofluid flow than in the regular fluid flow. | S.DAS S.CHAKRABORTY R.N.JANA O.D.MAKINDE | 2015 | Applied Mathematics and Mechanics(English Edition)2015，36，12： | 1 |
| 3 | Hall effects on hydromagnetic flow on an oscillating porous plate显示文摘In this paper, an analysis is made on the unsteady flow of an incompressible electrically conducting viscous fluid bounded by an infinite porous flat plate. The plate executes harmonic oscillations at a frequency n in its own plane. A uniform magnetic field H0 is imposed perpendicular to the direction of the flow. It is found that the solution also exists for blowing at the plate. The temperature distribution is also obtained by taking viscous and Joule dissipation into account. The mean wall temperature θ0(0) decreases with the increase in the Hall parameter m. It is found that no temperature distribution exists for the blowing at the plate. | S.L.Maji A.K.Kanch M.Guria R.N.Jana | 2009 | Applied Mathematics and Mechanics(English Edition)2009，30，4： | 0 |
