Heat Transport Analysis In Nanofluid Flows Through Different Geometeries

Abstract

Heat transfer applications span a wide range of industrial and technological fields, newlinemotivated by the necessity to efficiently regulate thermal energy. Conventional heat newlinetransfer fluids, such as water, mineral oil, and ethylene glycol, are widely employed in newlinediverse industries including power generation, chemical processing, microelectronics, newlineand climate control systems. However, their limited thermal conductivities hinder their newlineeffectiveness in heat exchange processes, thus requiring innovations like the newlineincorporation of nanoparticles to create nanofluids. These nanofluids significantly newlineenhance thermal conductivity and heat transfer properties. newlineThis thesis aims to examine the effects of temperature-dependent viscosity, thermal newlineconductivity, quadratic and cubic thermal radiation, magnetic fields, internal heat newlinegeneration/absorption, and viscous and ohmic dissipation on heat transfer phenomena newlinein nanofluids across various geometrical configurations, while delineating the newlineapplicability of the proposed model. newlineHeat transport scenarios have been analysed in practical applications using both newlinenumerical and analytical methods. The study highlights the impact of diverse physical newlineparameters on the heat and mass transmission mechanisms of nanofluids. The rates of newlineheat and mass transmission, as well as the coefficient of skin friction, are derived and newlineanalysed using graphs and tables. The concepts of entropy and Bejan number have been newlineemphasised. The applicability of such models has been prominently observed in newlineautomobile engineering, biomedical applications, microbial culture, and de-icing newlineof aircrafts. newline
