Повний текст джерелаMagnetohydrodynamic (MHD) boundary layer flow of an electrically conducting viscous incompressible fluid with a convective surface boundary condition is frequently encountered in many industrial and technological applications such as extrusion of plastics in the manufacture of Rayon and Nylon, the cooling of reactors, purification of crude oil, textile industry, polymer technology, metallurgy, geothermal engineering, liquid metals and plasma flows, boundary layer control in aerodynamics and crystal growth etc. Nanofluid is envisioned to describe a fluid in which nanometer-sized particles are suspended in conventional heat transfer base fluids to improve their thermal physical properties. Nanoparticles are made from various materials, such as metals (Cu, Ag, Au, Al, Fe), oxide ceramics (Al2O3, CuO, TiO2), nitride ceramics (AlN, SiN), carbide ceramics (SiC, tiC), semiconductors, carbon nanotubes and composite materials such as alloyed nanoparticles or nanoparticle core–polymer shell composites. It is well known that, conventional heat transfer fluids, such as oil, water, and ethylene glycol, in general, have poor heat transfer properties compared to those of most solids. Nanofluids have enhanced thermophysical properties such as thermal conductivity; thermal diffusivity, viscosity and convective heat transfer coefficients compared with those of base fluids like oil or water. Owing to their enhanced properties, nanofluids can be used in a plethora of technical and biomedical applications such as nanofluid coolant: electronics cooling, vehicle cooling, transformer cooling, computers cooling and electronic devices cooling; medical applications: magnetic drug targeting, cancer therapy and safer surgery by cooling; process industries; materials and chemicals: detergency, food and drink, oil and gas, paper and printing and textiles.

Повний текст джерелаEarth's magnetic field and rotation rate change on periods of several years.In this thesis it is investigated if and how such changes can be caused by modes (standing waves) in the liquid and conducting core.To do so, a model for a rapidly rotating and electrically conducting planetary core is developed that is able to handle non-idealized magnetic fields and a non-spherical boundary.We exploit the rapid rotation of the fluid to simplify our model, using the so-called quasi-geostrophic assumption, where the horizontal components of the velocity become invariant along the axis of rotation.By deriving such a model in a non-axisymmetric geometry, we are able to investigate the pressure torque exerted onto the core-mantle boundary by modes, which are linear solutions to the model.So-called torsional Alfvén modes are of particular interest, as they consist of differentially rotating geostrophic cylinders, potentially carrying axial angular momentum.These cylinders act against the tension of sheared radial magnetic field lines, showing their Alfvénic nature.In Earth's core they are assumed to have periods of a few years and they have been correlated to changes in the length of day on periods of about 6 yr.Our results suggest that the pressure torque associated to such torsional Alfvén modes is inefficient to explain the observed changes in Earth's length of day

A numerical study of flow and heat transfer from boundary layer flow driven by a stretching impermeable plate is proposed. The flow with electrically Newtonian fluid due to the continuous stretching sheet in the presence of a transverse uniform magnetic field was molded as an unsteady, viscous, and incompressible, taking into account the variation of fluid viscosity and thermal conductivity and including the effects of Ohmic heating due to electromagnetic work in the energy equation. The effects of viscous dissipation are neglected in heat flow process. The fluid viscosity is assumed to vary as an inverse linear function of temperature and the thermal conductivity is variable and considered to vary as a linear function of temperature. Similarity analysis with Chebyshev finite difference method (ChFD) was developed to solve the governing equations for mass, momentum and energy. Two different cases are considered, one corresponding to a infinite fluid medium surrounding the stretching sheet and the other, a finite fluid medium, i.e. thin liquid film on a stretching sheet. Graphical results for the effects of various parameters on the fluid velocity and temperature and the skin-friction coefficient and heat transfer rate are presented and discussed. Numerical results showed, for a given unsteadiness parameter, that the local heat transfer rate increases as Prandtl number increase, while it decreases as magnetic field strength, thermal conductivity parameter and viscosity parameter increase. The skin friction, for a given unsteadiness parameter, increases as magnetic field strength and viscosity parameter increase. The film thickness increases with the decreasing in unsteadiness parameter, magnetic field strength, and viscosity parameter in liquid film case. The free-surface temperature decreases with the increasing in unsteadiness parameter, magnetic field strength, Eckert number and viscosity parameter in liquid film case.

A linear stability analysis has been implemented for hydromagnetic flow, a viscous electrically conducting fluid between rotating concentric cylinders in the presence of a uniform axial magnetic field. The small gap equations with respect to three-dimensional disturbances of both axisymmetric and non-axisymmetric are derived and solved by a direct numerical procedure. Both of the two different types of boundary conditions, ideal conducting and non-conducting(or weakly conducting)walls are considered. Results are reported for the following three typical cases: (1)Hydromagnetic stability of dissipative Couette flow: Results show that the stability charqcteristics depend on the conductivity of the cylinders. (2)Hydromagnetic stability of current-induced flow between concentric cylinders: This flow is driven electromagnetically by the interaction of a superimposed radial current and a uniform axial magnetic field. (3)Hydromagnetic stability of current-induced flow between concentric rotating cylinders: The stability analysis of this flow is extended to the case where the primary flow includes a pressure gradient acting in the azimuthal direction. Results are reported for both weakly and ideal conducting cylinders.

Повний текст джерелаThe flow of electrically conducting fluids in the presence of a magnetic field has wide applications in science, engineering and technology. Examples of the applications include industrial processes such as the cooling of reactors, extrusion of plastics, purification of crude oil, medical applications, aerodynamics and many more. The induced magnetic field usually act as a flow control mechanism, especially under intense heat. In this study a couple stress fluid in a channel will be used as the working fluid. Channel flow and heat transfer characteristics of couple stress fluids find applications in processes such as the extrusion of polymer fluids, solidification of liquid crystals, cooling of metallic plates in a bath, tribology of thrust bearings and lubrication of engine rod bearings. One major characteristic that distinguishes the couple stress fluid from other non-Newtonian fluids is the inclusion of size-dependent microstructure that is of mechanical significance. As such, the couple stress constitutive model is capable of describing the couple stresses, the effect of body couples and the nonsymmetric tensors manifested in several real fluids of technological importance. A fully developed laminar magnetohydrodynamic (MHD) flow of an incompressible couple stress fluid through a vertical channel due to a steady-periodic temperature on the channel plates is investigated. Specifically, the effects of couple stresses and internal heat generation on MHD natural convection flow with steady-periodic heat input, the impact of magnetic field induction on the buoyancy-induced oscillatory flow of couple stress fluid with varying heating and a mixed convective two dimensional flow of unsteady MHD couple stress fluid through a channel field with porous medium are studied. Analytical methods and the semi-analytic Adomian decomposition method will be used to solve the resulting non-linear differential equations governing the flow systems. Useful results for velocity, temperature, skin friction and Nusselt number are obtained and discussed quantitatively. The effects of the various flow governing parameters on the flow field are investigated.

Based on the thermodynamics second low, this thesis aims to analyze the entropy generation in a fully developed laminar flow of conducting liquid inside a channel that is made of two inclined parallel uniformly heated plates under the action of a transverse magnetic field. The effect of heat generation by viscous dissipation is included in the analysis. According to Adrian Bejan EMG (entropy generation minimization) technique , the dependence of local entropy generation on Hartman number Ha, Brinkman number Br and viscous dissipation parameter BrΩ-1 are discussed numerically. This article observes that entropy generation increases as the value of Harman number, Brinkman number and viscous dissipation parameter increase.

The unsteady hydromagnetic chemically reacting mixed convection MHD ow over a permeable stretching sheet embedded in a porous medium with thermal radiation and heat source/sink is investigated numerically. The original partial di erential equations are converted into ordinary di erential equations by using similarity transformation. The governing non-linear partial di erential equations of Momentum, Energy, and Concentration are considered in this study. The e ects of various physical parameters on the velocity, temperature, and species concentration have been discussed. The parameters include the Prandtl number (Pr), Magnetic parameter (M), the Schmidt number (Sc), Unsteady parameter (A), buoyancy forces ratio parameter (N), Chemical reaction (K), Radiation parameter (Nr), Eckert number (Ec), local heat source/sink parameter (Q) and buoyancy parameter due to temperature ( ). The coe cient of Skin friction and Heat transfer are investigated. The coupled non-linear partial di erential equations governing the ow eld have been solved numerically using the Spectral Relaxation Method (SRM). The results that are obtained in this study are then presented in tabular forms and on graphs and the observations are discussed.
