چکیده
Recently, Sengupta and Ghosh [“Linear stability of a rotating channel flow subjected to static magnetic field,” Phys. Fluids 34, 054116 (2022)] published linear analysis pressure-driven flow, which is subject rotation around spanwise axis uniform field applied in the same direction. Unfortunately, formulation magnetohydrodynamic part problem contains an elementary error, makes obtained results unphysical. The error due unfounded omission electric potential contribution induced current which, thus, does not satisfy charge conservation.

Effect of Magnetic Field on the Rotating Flow in a Similar Czochralski Configuration
We present a numerical study of the rotating flow generated by two rotating disks in co-/counter-rotating, inside a fixed cylindrical enclosure similar to the Czochralski configuration (Cz). The enclosure having an aspect ratio A = H/Rc equal to 2, filled with a low Prandtl number fluid (Pr = 0.011), which is submitted to a vertical temperature gradient. The finite volume method has been used ...

The use of magnetic fields in targeted drug delivery, especially for treatment of cancers and tumoral regions, is one of the significant techniques in the field of modern methods of treatment. Considering that many vital biological tissues have been located deep in the body, then for targeted drug delivery and effective treatment in these tissues, it is required to bring therapeutic agent to th...
متن کاملNanofluid Flow in a Semi-porous Channel in the Presence of Uniform Magnetic Field
In this paper, the problem of laminar nanofluid flow in a semi-porous channel is investigated analytically using Homotopy Perturbation Method (HPM). This problem is in the presence of transverse magnetic field. Here, it has been attempted to show the capabilities and wide-range applications of the Homotopy Perturbation Method in comparison with the numerical method in solving such problems. The...

The flow of fluids with different viscosities, subjected to an interfacial perturbation, can lead to fingering and migration. Both Refs. 2 and 3 refer to fingers in twodimensional studies, which would correspond to sheets in three dimensions. Figure 19 of Ref. 3 shows a sequence of interface positions for initial amplitude 0.05, wave number a5p/2, Reynolds number R15500, viscosity ratio m50.5, ...
