The associated heat transfer modes are mixed convection in the fluid and conduction in the wall. Thermophysical fluid properties are thermo-dependant. A three dimensional numerical simulation is conducted, The finite volumes method with a second order scheme in time and space is adopted to resolve this problem, Two different heating conditions are considered: strenght of electrical current of 45 an 65 Amperes which correspond to two various Graschof numbers: Gr=244492 and 510000. The other control parameters such Reynolds and Prandtl numbers are fixed constant: Re=606 and Pr=8. The transversal secondary flow in a cross section is induced by a bouyancy effect along the duct. In a cross straight section, two contra-rotative cells are observed. These rolls are separated by the median vertical plane. The center of these rolls moves downward when the axial coordinate increases. The major points of this work consist first at a qualitative and a quantitative comparison between the results obtained by the first and the second order schemes, then a comparison with experimental results is achieved. It is to be noted that, qualitatively the first and the second order schemes give similar results but quantitatively the results obtained by the first order scheme are closer to the experimental results. These differences induce more important discrepancies of the axial Nusselt number. This is due to the fact that the second order scheme needs a more refined mesh than the first order on one hand and on other hand in the experimental results the uncertainties and the heat losses are not known. Taking into account these comments could reduce the difference between the obtained results.

Newtonian, incompressible and laminar flow with temperature dependent physical properties. The single-phase approach is adopted. The outer cylinder is uniformly heated while the inner cylinder is adiabatic. The flow and thermal fields are modeled by the continuity equation, the three momentum equations and the energy equation of the nanofluid with appropriate initial and boundary conditions using a cylindrical coordinate system. The nonlinear differential equations with partial derivatives are solved numerically by the finite volume method with a spatio-temporal discretization of the second order. The SIMPLER algorithm was used to solve the speed-pressure coupling. A complete parametric analysis on the effect of the presence of nanoparticles dispersed in the fluid such as volume fraction, type and shape on the development of thermal and hydrodynamic fields. The dimensionless control parameters that control the problem under consideration are the Reynolds number, the Prandtl number and the Grashof number, a radius ratio set to 2. For the volume fraction ranging from 0 to 10%, six nanoparticles Types, two metallic types Cu and Ag, three ceramics Al2O3, TiO2 and CuO. Also four forms of the nanoparticles are the shape the spherical shape, Blade, Cylinder, Platelet and Bricks shape. The study of these effects on heat transfer in a annular cylinder without fins and with fins is the main objective of this study. The results concerning the different cases studied for the effect of the volume fraction of the different nanofluids shows that the increase in the volume fraction increases the heat transfer along the annular duct. The axial and mean Nusselt numbers obtained are also higher in the case of the nanofluid (Ag / water). They also show that the use of the Ag nanoparticle induces a better improvement of the heat transfer followed by Cu, Al2O3, CuO at the end TiO2. Regarding the effect of the shape of the nanoparticles Blade shape greatly improves the heat transfer compared to other shapes. A generating correlation expresses the average Nusselt number for the different shapes as a function of the volume fraction proposed: Nu moy = a + bϕ + cϕ2. Another correlation which expresses the average Nusselt number of the nanofluid (TiO2/water) and the hybrid nanofluid (Ag-TiO2 / water) as a function of the number of Grashof, Prandtl and the volume fraction: The use of the heat-generating fins, attached longitudinally to the outer cylinder and immersed in the nanofluid, greatly improves the heat transfer compared to those of a nonfinned horizontal duct dû to the increase in the exchange area between The nanofluid and the fins in the annular space.

For this reason, two studies on this subject have been carried out. In the first study, a numerical study was carried out on heat transfer by natural convection using two nanofluides inside a horizontal cylindrical enclosure with partial heating of its lower part at constant temperature or constant heat flux, the length of the heat source is changed from 5% to 25% of the total perimeter of the enclosure, the rest of the unheated parts of the bottom wall are considered as adiabatic, the two side parts of the enclosure are considered at a low constant temperature, each one of them has a length of 25% of the total perimeter of the enclosure, the top part of the enclosure is considered as adiabatic, it has a length of 25% of the total perimeter. To analyze the effect of using nanofluids with different particles volume fractions on heat transfer inside cylindrical horizontal enclosures, two nanofluids (Cu-water, TiO2-water) were used with volume fraction of nanoparticles being varied in the range of 0 corresponding to pure water) to 0.05. The steady state forms of Navier-Stokes equations and the equations of conservation of mass and energy in twodimensional cylindrical coordinates have been solved by the finite volume method and the SIMPLE algorithm was used for the pressure-velocity coupling. The Rayleigh number was varied in the interval 103 to 106. This research is characterized by a detailed analysis of the effect of changing both the Rayleigh number, the heated length and the value of nanoparticles volume fraction on the dynamic and thermal fields, on the percentage enhancement of the average Nusselt numbers, and also on the variation of the temperature and the vertical velocity component at the vertical and horizontal central lines of the enclosure. The results obtained were summarized in the form of correlation equations of the average Nusselt number as a function of the heated length, the Rayleigh number and volume fraction for both types of nanofluids. In the second study, a numerical study was carried out on the effect of using two techniques for the optimization of heat transfer by natural convection in a three-dimensional spherical enclosure of solar water heater. The outer wall (solar collector) is considered as a heated wall at a constant temperature, the wall which is located behind the solar collector is considered as adiabatic wall. In the enclosure there is a spiral tube, its wall is under a low temperature which increases linearly in terms of enclosure height. The first technique is to exploit nanotechnology using two types of nanofluids Cu-Water and CNT-Water, to improve the heat transfer in the enclosures of spherical solar water heaters, the volume fraction of nanoparticles was varied in the range of 0 (corresponding to pure water) to 0.05. The second technique involves making geometric modifications to the enclosure of spherical solar water heater to improve the natural convection heat transfer, these modifications consist in creating concentric annular orifices in the lower part of the internal adiabatic wall of the solar water heater, the number of annular orifices varies from 1 to 6. The Rayleigh number was varied in the interval 104 to 106. The steady state forms of Navier-Stokes equations and the equations of conservation of mass and energy in three-dimensional spherical coordinates have been solved by the finite volume method. The SIMPLE algorithm was used for the pressure-velocity coupling. This research is characterized by a detailed analysis of the effect of changing both the Rayleigh number, the number of annular orifices and the value of nanoparticles volume fraction on the dynamic and thermal fields and on the heat transfer and its percentage improvement. The results obtained were summarized in the form of correlation equations of the average Nusselt number as a function of the Rayleigh number, the number of annular orifices and the volume fraction of the nanofluid. Through the results obtained in all the studies carried out in the frame of this doctoral thesis, a very important theorem has been reached on the improvement of heat transfer by natural convection in enclosures. The application of this theorem can revolutionize the field of performance improvement of various thermal engineering systems whose operating principle depends on heat transfer by natural convection.
