Abstract

Title of the thesis is HEAT AND MASS TRANSFER EFFECTS IN MICROPOLAR newlineFLUID: A THEORETICAL STUDY newlineHeat and mass transfer phenomena play a crucial role in various engineering newlineand scientific applications. Understanding the intricate mechanisms and newlinebehavior of fluids in these processes is of utmost importance. The present newlinethesis aims to investigate the heat and mass transfer characteristics of newlinemicropolar fluids and their implications in various practical scenarios. newlineMicropolar fluids exhibit unique characteristics due to the presence of newlinemicrostructure in their flow field. Unlike classical Newtonian fluids, newlinemicropolar fluids possess additional degrees of freedom associated with newlinethe rotational motion of microelements within the fluid. This distinct newlinebehavior has a significant influence on the overall heat and mass transfer newlineprocesses. newlineThe research begins by establishing the mathematical framework to newlinedescribe the behavior of micropolar fluids. The governing equations, newlinederived from the principles of continuum mechanics and thermodynamics, newlineare presented. These equations take into account the momentum, angular newlinemomentum, energy, and mass conservation, along with the constitutive newlinerelations characterizing the micropolar nature of the fluid. newlineTo analyze the heat transfer effects in micropolar fluids, the thesis newlinefocuses on the study of thermal conduction and convection. The conduction newlineprocess is investigated by solving the heat conduction equation, accounting newlinefor the micropolar properties. Analytical and numerical techniques are newlineemployed to explore the effects of microinertia and micro-rotation on heat newlinetransfer rates and temperature distributions. newlineFurthermore, the convective heat transfer behavior of micropolar fluids is newlineinvestigated. The study explores the flow of micropolar fluids over various newlinegeometries, such as flat plates, cylinders, and spheres. The heat transfer newlinecharacteristics, including the Nusselt number, heat transfer coefficient, newlineand temperature distribution, are examined under different flow newlineconditions.
