PhysiqueTags : Photothermique Simulation numérique Convection forcée Convection mixte Conduit annulaire nanofluide (eau / Al2O3) Numerical simulation forced convection Mixed Convection annulus duct nanofluid (water/Al2O3) ????? ?????? ????? ??????? ???????? ???????? ????????? ????????? ?????????)???/ Al2O3) Index. décimale : 530 Physique Résumé : This research is a 3D computer simulation of fluid flows, combined to heat transfer in a forced and mixed convection mode, for a permanent and steady laminar flow through an annular duct made up of two horizontal and concentric cylinders. While the inner cylinder is adiabatic, the outer cylinder is subjected to a constant parietal heating. The annulus duct is traversed by a nanofluid laminar flow composed of a fluid base (water) and nanoparticles of aluminum oxide Al2O3 with constant physical properties regarded as incompressible and
Newtonian. This physical problem is modeled by mass conservation equations, by movement and energy amounts in a cylindrical coordinate system accompanied by appropriate boundary conditions. Different approaches were developed, such as the monophasic and the biphasic approaches, to which belong the fluid volume models, the mixing model and the Eulerian model.
These equation systems were solved as to the single-phase model by means of the finite volume method with a second-order spatial and temporal precision and the SIMPLER algorithm for the sequential solution of equations. The dynamic and thermal fields are obtained for various Reynolds number values, ranging from 500 to 2000, reaching (1%, 4%,8%) for different concentrations of nanoparticles, and between (0, 104 and 105) for different numbers of Grashof. The results show that the nanofluid behavior, whether in a forced convection mode or in mixed convection mode are, from both a hydrodynamic and a thermal points of view, characteristics of a trend similar to the behavior of a conventional fluid. In a forced convection, dynamic and thermal fields reflect radial velocity and temperature
gradients, as well as a Nusselt number with asymptotic behavior at the output. In a mixed convection, the cell structure and the lamination temperatures through a straight section appear with an increasing number of Grashof, giving rise therefore to an increase in the Nusselt number, and thus to a better heat transfer.

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.

This study presents a numerical simulation of the three dimensional laminar mixed convection between two elliptical horizontal cylinders using temperature dependent physical properties.
The inner cylinder is uniformly heated whereas the outer cylinder is adiabatic. The flow and thermal fields are modeled by the continuity, momentum and energy equations with appropriate initial and boundary conditions using an elliptical coordinate system. The model equations are numerically solved by a finite volume numerical method with second order accurate spatiotemporal discretizations. For the considered geometric, dynamic and thermal controlling parameters, it is found that the realistic consideration of the mixed convection with variable physical properties gives physically sound flows and thermal fields that are qualitatively and quantitatively different from those of forced convection with temperature dependent properties and those of mixed convection with constant properties; the obtained Nusselt number is also higher in this case. The heat transfer enhancement obtained by considering natural convection within mixed convection with temperature dependent physical properties increases with the increased Grashof number which is proportional to the heat flux imposed at the surface of the
inner cylinder.Diplôme : Doctorat en sciences En ligne : ../theses/physique/ZER6483.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=9542 Effet des propriétés thermophysiques variables sur la convection mixte dans l’espace annulaire entre deux cylindres elliptique horizontaux [texte imprimé] / Khalil Zerari, Auteur ; M.

metallic nanofluids and water-(AlO3, TiO2) metal oxides. The fluids are supposed
incompressible and Newtonian. The equations governing the flow and heat transfer have
been solved using the finite volume method. A house code in FORTRAN has been

Génie MécaniqueTags : Convection mixte Canal horizontal Refroidissement nanofluide Ailettes Mixed convection horizontal channel Cooling nanofluid fins ????? ??????? ???? ????? ????? ???? ??????? ???????? Index. décimale : 620 Génie Mécanique Résumé : Heat transfer is very important for good design and reliable operation of a system.
Reliability and system performance are highly dependent on the operating temperature,
in particular, in electronic equipment. Several cooling methods have been proposed in
order to improve the heat transfer. These techniques include two: which consists in
grafting blades offering a greater contact surface with the environment; and which
consists of using nanofluids comprising metallic particles or carbon nanotubes. The
latter is currently present the best solution.
In the first part of the thesis, a numerical study of 2D laminar mixed convection in
a horizontal channel with three fins nanofluid has been carried out made. The influence
of Reynolds and Richardson numbers and concentration of nanoparticles (Al2O3, Cu, Ag
and TiO2) dispersed in a base fluid (water), on the flow and thermal fields is presented.
A computer code in Fortran, based on finite volume method was used to simulate 2D
flow with heat transfer. The results indicate that the addition of nanoparticles in pure
water can improve the cooling performance, in particular, low Richardson number. The
influence of the solid volume fraction on increasing the heat transfer is more sensitive to
higher values of Reynolds number. Although, the addition of nanofluids (TiO2 and
Al
2O3) also increases heat transfer, their influence is not important for Cu-Ag-water and
water.
The second part is to find an optimal geometry for good cooling. Numerical
calculations were carried out using the software ""FLUENT 6.3"" to simulate 3D laminar
mixed convection flow in a channel containing fins with nanofluid. The effects of
Reynolds number, height, and distance between the fins are presented and discussed.
