Fluid Mechanics2

This handout complies with the ministerial outline for the Fluid Mechanics 2 course offered in third year S5_ Bachelor's degree LMD at Algerian universities. It is a continuation of the course given second year S3_ Bachelor's degree LMD .
Fluid mechanics is one of the most difficult disciplines to assimilate. It requires both theoretical mathematical knowledge (tensor calculus, divergence and gradient operators......) and basic physics (Archimede force, Bernoulli equation, notion of similarity, etc.).
This course is structured in three chapters. The first deals with fluid kinematics, in which theoretical mathematical knowledge is first used (differential equations, divergence and gradient operators, integrals), the conservation of mass equation and 2D plane flows in the incompressible and irrotational case, as well as the complex potential function.
The second chapter deals with integral conservation laws. The Reynolds transport theorem is applied to the equation of continuity of momentum and energy.
The notion of dimensional analysis and similarity seems essential and this is the subject of the third chapter.

Numerical Analysis of Natural Convection in an Annular Cavity filled with Hybrid Nanofluids Under Magnetic Field

This paper presents a numerical study of natural convection in an annular cavity filled with a hybrid nanofluid under the influence of a magnetic field. This study is significant for applications requiring enhanced thermal management, such as in heat exchangers, electronics cooling, and energy systems. The inner cylinder, equipped with fins and subjected to uniform volumetric heat generation, contrasts with the adiabatic outer cylinder. This study aims to investigate how different nanoparticle combinations (Fe3O4 with Cu, Ag, and Al2O3) and varying Hartmann and Rayleigh numbers impact heat transfer efficiency. The finite volume method is employed to solve the governing equations, with simulations conducted using Fluent 6.3.26. Parameters such as volume fraction (ϕ2 = 0.001, 0.004, 0.006), Hartmann number (0 ≤ Ha ≤ 100), Rayleigh number (3 × 103 ≤ Ra ≤ 2.4 × 104), and fin number (N = 0, 2, 4, 6, 8) are analyzed. Streamlines, isotherms, and induced magnetic field contours are utilized to assess flow structure and heat transfer. The results reveal that increasing the Rayleigh number and magnetic field enhances heat transfer, while the presence of fins, especially at N = 2, may inhibit convection currents and reduce heat transfer efficiency. These findings provide valuable insights into optimizing nanofluid-based cooling systems and highlight the trade-offs in incorporating fins in thermal management designs.

Numerical simulation of hybrid nanofluid in PV/T solar panel

This work represents a 3D numerical study of heat transfer of an hybrid nanofluid in the tube of a hybrid photovoltaic solar panel PV/T. The Fluent 6.3.26 software packages is used to carry out the numerical simulations. The hybrid nanofluids composed of TiO2-Cu/water and TiO2-Ag/water suspension. The properties of these hybrid nanofluids can be influenced by the type, size, and concentration of nanoparticles. As independent control factors, the nanoparticles concentration ratio in the hybrid nanofluid were employed. The thermal efficiency and the temperature of the PV/T components were employed as dependent parameters. According to the simulation data, the thermal efficiency and the temperature of the PV/T system increased by increasing the volume concentration of the nanoparticles. The hybrid nanofluid TiO2-Ag/water gives the best efficiency than TiO2-Cu/water

A New Study on the Effect of the PartialWake Generated in a Wind Farm

In this article, we present an investigative study on the often-overlooked partial wake phenomenon in previous studies concerning wind farm configurations. A partial wake occurs when a portion of the actuator disk of a downstream wind turbine is affected by the wake of another upstream turbine. This phenomenon occurs in addition to the full wake, where the entire upstream turbine is affected by the wake of the frontal turbine, also leading to a decrease in wind speed and consequently a reduction in power production. The proposed study is based on measuring the power generated by the area swept by the wake of an array of turbines in a wind farm. To accomplish this, we integrate the linear wake model of Jensen, the specifications of the ENERCON E2 wind turbine, and the wind farm data into Matlab-developed software (version 18) to perform the calculations. In a concrete application, this proposed method is validated by reproducing the previous works that neglected the partial wake in wind farm configurations. The simulation results obtained are analyzed, compared, and discussed under similar operational conditions.

Conception et Réalisation d'un séchoir solaire à panneau thermique à ailettes destiné aux produits agroalimentaires

Le séchage est l'une des principales méthodes de conservation des produits agricoles et alimentaires afin d'assurer une longue durée de conservation, de faciliter le transport et d'assurer la disponibilité du produit en cas de pénurie de ce produit frais sur le marché national.
Dans ce travail, nous avons créé un séchoir solaire indirect qui fonctionne par convection naturelle, à travers lequel nous avons mené plusieurs expériences à différents jours sur différents types de produits alimentaires (pommes de terre, tomates, oignons)
Ce type de séchoir peut être réalisé en différentes tailles et est notamment utilisé pour les produits très sensibles au rayonnement solaire.
Et particulièrement adapté. Pour le séchage des produits alimentaires, il a l'avantage de mieux préserver les propriétés des aliments
L'objectif de ce travail à travers ces expérimentations, est d'une part d'étudier la cinétique de séchage, et d'autre part, l'effet de la température de séchage sur la qualité du produit agro-alimentaire pomme de terre.
Au terme de cette étude, nous avons conclu que la température de l'air de séchage est le facteur le plus important affectant la cinétique de séchage.

NUMERICAL SOLUTION ON MIXED CONVECTION FLOW OF NANOFLUID AROUND A FINNED ANGULAR SECTOR OF HEAT SINK

The aim of this study is to investigate mixed convection flow of nanofluid around a three-dimensional (3D) finned angular sector of heat sink by means of numerical simulations. The finite-volume method is used to solve the governing equations of mass, momentum, and energy conservation. The Brownian motion of the nanoparticles in the base fluid is explicitly taken into account in the thermal conductivity model (Patel model). A parametric study is carried out to examine the effects of several key parameters on the rate of heat transfer; the angular sector apex angle, the volume fraction of suspended nanoparticles (0 ≤ φ ≤ 0.09), the Richardson number (Ri = Gr/Re2), and the size of the nanoparticles diameter (5, 20, 60, and 100 nm). It is shown that for a fixed low Richardson number Ri, the rate of heat transfer increases with the volume fraction of the nanoparticles, as forced convection mechanism is dominated. The heat-transfer enhancement is obtained for the nanofluid water/TiO2 rather than the water/Cu at higher nanoparticles volume concentration and highest Richardson number. Moreover, the Maxwell thermal conductivity model resulted in a maximum enhancement in the case of nanofluid water/TiO2 than that of water/Cu, whereas the nanofluid water/ Cu gives better heat-transfer enhancement at small particles than that of water/TiO2. It is observed too that the nanoparticles' diameter does not have a significant effect on the temperature field.

The governing equations of mass, momentum and energy equations for both the fluid and the solid are solved by the finite volume method, using the commercially available CFD software Fluent 6.3.26. The effect of the size of the nanoparticles on the rate of heat transfer is carried out and investigated. The study has been conducted considering two nanofluids of based water with Al2O3 and TiO2 nanoparticles for a solid volume fraction (0≤ ϕ ≤ 0.09) and nanoparticles diameter of (5nm,20nm, and 80nm) at Rayleigh number Ra=12000. Results have shown that adding nanoparticles in the base fluid have produced an increase of the rate of heat transfer. The nanofluid water/Al2O3 gives better heat transfer enhancement at small particles diameter than the nanofluid Water/TiO2

Numerical investigation of convective heat transfer of nanofluid in heat exchanger

This work presents the numerical results of the mixed convective heat transfer of a three-dimensional flow around a radial heat sink composed of horizontal circular base fitted with rectangular fins. The governing equations of mass, momentum and energy equation are solved by the finite volume method using the commercially available CFD software Fluent 6.3.26. The circular base of the heat sink is subjected to uniform heat generation, the flow enters through the sides of the heat sink around the fins then the heat is transmitted from the base to the fins afterward the fluid. In this study two fluids are utilized, in the first case, the air for the following Reynolds numbers Re=600,900,1200 and a Grashof number Gr=3.7x106, in the second case a water-based nanofluid for which two types of nanoparticles (Cu and Al2O3) are carried out for Re=25 and a Richardson number Ri=2.7(Ri=Gr/Re2). The effect of the number of the fins of the heat sink as well as the type and the volume fraction of nanoparticles of the nanofluid were investigated. Results have been presented for N=15 and N=20 fins. The effect of the nanoparticles concentrations and the number of fins on the temperature in the heat sink and the Nusselt number has been studied.

Effect of Fin Parameters in Cylindrical and Divergent Duct under Natural Convection S.

In this paper, we propose a numerical study of the natural convective heat transfer flow in a three dimensional
cylindrical and divergent annular duct. The inner cylinder subjected to a volumetric heat generation is fitted
with longitudinal fins. The governing equations of mass, momentum and energy equation for both the fluid and
the solid are solved by the finite volume method, using the commercially available CFD software Fluent. The
effect of the inclination angle ϕ of the divergent and the fin parameters on the profiles and the contour fields of
temperature and velocity as well as the average Nusselt number ratio were investigated for ϕ=0°,15°,23° and
45°and several fins, N=1,2,3 and 4. The Simulations were carried out in the range of Rayleigh numbers
(Ra = 100 to Ra=6.3x104). The results reveal that the increasing of the inclination angle of the divergent and
the number of fins enhance the heat transfer.
