Unsteady Magnetohydrodynamic Oscillatory Nanofluid Flows in Asymmetric Channel

Abstract

This thesis investigates the nonlinear dynamics of magnetohydrodynamic (MHD) newlineoscillatory nanofluid flows through asymmetric channels, with a particular emphasis newlineon temperature sensitivity, viscous dissipation, nanofluid composites and the impact of newlinevarious physical phenomena. Addressing significant gaps in current research, this study newlineexplores the behavior of mono, hybrid and ternary nanofluids with diverse nanoparticle newlineshapes and compositions - such as copper, silver, gold, carbon nanotubes (CNTs), newlineboron nitride nanotubes (BNNT) and cobalt ferrite - under varying external conditions, newlineincluding magnetic fields, thermal radiation and porous media effects. The work is newlinemotivated by the need to characterize complex fluid behaviors relevant to industrial newlineand biomedical applications, where intricate flow patterns and thermal properties are newlineinfluenced by channel geometry, viscosity variations and external forces. newlineThis theoretical study, based on computational fluid dynamics (CFD), provides a newlinecomprehensive analysis of both Newtonian and non-Newtonian fluids within MHD newlineoscillatory flows. The study evaluates te effects of viscous dissipation, thermo-duffuion, newlinediffusion-thermo, nanoparticle shape factor and chemical reactions within the fluid models, newlineillustrating each fluid type s response to complex external conditions newline
