Scrutiny of induced magnetic field and Hall current impacts on transient hydromagnetic nanofluid flow within two vertical alternative magnetized surfaces

Abstract

The main goal of this presentation is to scrutinize the flow behavior of transient hydromagnetic Ti 6 Al 4 V-H 2 O-based nanofluid flow within a symmetric channel bounding a uniform porous medium with induced magnetic field and Hall current effects. The nanofluid is assumed to be partially ionized and its flow is influenced due to the presence of a strong transverse applied magnetic field domain. Due to this reason, induced magnetic field and Hall current impacts are focused in this study. The right surface of the channel is considered to be magnetized and oscillating vertically while the left surface is non-magnetized and stationary. The flow model is transformed to a similar model by the use of dimensionless transformations and leading resulting equations are solved analytically with the aid of variable separable method. The results are demonstrated with the assistance of Mathematica software and also validated with the existing results in the literature. This study is significant in analyzing the flow nature of highly electrically conducting nanofluids. An important flow characteristic observed from this study is that by increasing the volumetric concentration of nanoparticles in the fluid, the induced magnetic field is increased due to the rise in electrical conductivity of the fluid. Furthermore, the Hall current and magnetic diffusion brings a significant decrement in induced magnetic field along the main flow.
