博士 === 國立暨南國際大學 === 土木工程學系 === 100 === Chap. 1 introduces the general applications in nanofluid and useful general mathematic formulae onto geometric configurations. In Chaps. 2 and 3, by taking the balance of the flow rate in a vertical double-passage channel, the effect of inertia, buoyancy, porous medium, micropolar fluid and viscous dissipation have been investigated via the control of flow rate. Chap. 4 studies the effect of magnetic field, viscous dissipation, non-uniform heat source and/or sink and thermal radiation on flow and heat transfer in a hydromagnetic liquid film over an unsteady stretching surface with prescribed heat flux condition. Taking into account of the Brownian diffusion and thermophoresis of slip mechanisms in the concentration equation, Chapter 5 investigates the flow, heat and mass transfer in two geometric configurations: I. Near a Rotating Disk and II. Over a Bi-directional Stretching Surface and the results illustrate that the correlations of physical parameters for the heat and mass transfer rates have been developed on a regression analysis. With the nanoparticle volume fraction being specified, different types of nanoparticles, namely, silver Ag, copper Cu, alumina Al2O3, and titanium TiO2 with water as the base fluid are considered in Chapter 6 under two geometric configurations which are III. Near a Rotating Disk and IV. Over a Bi-directional Stretching Surface. The velocity, temperature and concentration profiles, the hydrodynamic and thermal boundary layer thickness, the surface friction coefficients, heat and mass transfer rate are demonstrated and discovered with the effect of parameters. Chap. 7 concludes the results of the present studies and gives suggestion for the future works.
