dc.description.abstractResearch and advancements in the area of nano-science have caught attention since last two decades. In general, fluid flow analysis is a part of fluid mechanics that deal with analysis (called peristalsis) of fluids like food, blood, chime, urine etc. in distensible vessel (e.g., arteries, veins, arterioles, venules, and capillaries etc.). One class of fluids known as nanofluids contain nanometer-sized particles, encompass wide applications in medical science, energetics, biology, engineering processes etc. Nanofluids possess enhanced thermo-physical properties like thermal conductivity, velocity, pressure gradient, pressure rise, shear stress etc. The study of magnetic field effects on moving nanofluids is called magnetohydrodynamics. Previously, many articles have been presented on analysis of peristaltic flow of nanofluids. However, many aspects related to peristaltic flow like temperature-dependent viscosity, nanoparticle shape effects in the existence or nonexistence of magnetohydrodynamics, velocity and thermal slip effects by the transverse magnetic field have yet not been explored. Consideration of these aspects make analysis scenario more practical and real which helps in further enhancement for thermo-physical performance of nanofluids. The present thesis addresses the investigation of nanofluid flow by incorporating temperature-dependent viscosity, shape effects, presence of magnetohydrodynamics and slip effects in transverse magnetic field. The effect of heat source/sink parameter, Grashof number, viscosity parameter and nanoparticle volume fraction on temperature, velocity, pressure gradient, pressure rise and wall shear stress distributions is analyzed for different nanofluid suspensions. Firstly, aforementioned analysis on nanofluid flow in vertical tube is presented. Secondly, as a further step, nanofluid flow with the interaction of shape factor is analyzed. Three types of shape factor, i.e., cylinder, platelets and bricks are discussed. Thirdly, an analytical approach is presented to analyze nanoparticle shape effects on flow in the presence of magnetohydrodynamics. Finally, the investigation of slip effects on nanofluid flow under the influence of transverse magnetic field through the vertical parallel plates is discussed. Results of all presented developments have been certified for consistency with existing concepts related to peristaltic transport of nanofluids. The presented results will be helpful in enhancing the nanofluid characteristics related to applications like medical science, energetics, biology, engineering processes etc.en_US
