Nanofluid Heat Transfer Phenomena Through Porous Media

Abstract

The current thesis entitled quotNANOFLUID HEAT TRANSFER PHENOMENA THROUGH POROUS MEDIAquot is focused on the computational exploration of two- and three-dimensional fluid flow problems through porous media. This thesis contains theoretical and numerical exploration of non-Newtonian fluids and heat transfer over the different stretching surfaces. The significant characteristics of heat and mass transfer through isotropic and anisotropic porous media are seen in numerous simulation phenomena of nuclear reactors and furnace, energy storage systems, slat gradient solar reactors, molten salt energy storage tanks, and heat exchangers. The effect of radiative heat and mass transfer through permeable stretched surface is also included in the current thesis. Also, the boundary layer flows are implemented in polymer extrusions, plastic sheet drawing, paper industry, biofluid movement, artificial film manufacture, data storage, magnetohydrodynamics (MHD) generators, magnetic material processing, and many other industries. newlineResearch on heat transmission via porous media is essential because it has many applications in a variety of engineering and environmental contexts. Porous media, such as geological formations, heat exchangers, and biological tissues, are characterised by their complex internal structures and transport properties. Enhancing heat transfer in porous media has become more feasible in recent years with the use of nanofluids, which are designed suspensions of nanoparticles in ordinary fluids. newlineThe proposed study addresses the MHD boundary layer flow of various non-Newtonian fluids across a porous medium. This research looks at the physical significance of flowing fluid and the heat and mass transfer characteristics of Casson fluid, Williamson fluid, Maxwell fluid, and Micropolar fluid across porous media under distinct physical as well as thermal boundary conditions. Research on non-Newtonian fluids is extremely important when considering their applications in biomechanics and engineering.
