Index. décimale : 626 Génie Climatique Résumé : The techniques of natural ventilation count among the best solutions, which are used to ensure the thermal comfort of occupants as well as to reduce the energy bill. This thesis aims to evaluate the use of crossing natural ventilation and one-sided ventilation in order to predict the best adapted technique. Another objective of this thesis is the study the heat transfert in a vertical channel asymmetrically heated in order to study the influence of inclination of the not heated wall on natural convection and predict the ideal angle for a better energy efficiency. The results of this work has proved that the technique of cross ventilation is undoubtedly the
best solution in order to avoid all causes that degrade building quality and promote the comfort of occupants. It has also been prove that the inclination of -10° (of the non-heated wall) seemed with being the optimal angle ensuring greatest energy fficiency.

Index. décimale : 626 Génie Climatique Résumé : This thesis is a part of a project searching to understand the double-skin fagade function by intergrating of an opening used for secondary ventilation. It deals with the natural convection into the vertical double-skin fagades. We modelled our system by a vertical channel asymmetrically heated with uniform heat flux density. The mass conservation equations of momentum and energy are solved using the finite volume method. Numerical simulations are performed using Ansys Fluent CFD software. The results of the flow structure presentation allow to observe the impact of the opening size and position on the recirculation zone and the mass flow rate at the channel entrance. In addition, thermal results presentation shows that the presence of the opening in the bottom of the channel increases the heat transfer more than the other positions do.

Langues : Français (fre) Tags : combustion turbulente simulation numérique flamme de diffusion turbulente enrichissement par de l’hydrogène turbulent combustion numerical simulation CFD turbulent diffusion flame hydrogen blend ?????? ???? ???????? ??????? ???? ??? ????? ???? ????? ??????????? Index. décimale : 530 Physique Résumé : Most of the energy produced and used in the world comes from fossil fuels. The combustion of these fuels cause the emission of significant quantities of greenhouse gases as well as different types of pollutants such as CO, NOx and other pollutant particles. The addition of hydrogen in hydrocarbons appears to be a promising way to reduce these emissions. Indeed, it
has been demonstrated by several authors that the addition of certain quantities of hydrogen in hydrocarbons improves combustion performance (improves flame stability, pollution, etc). As hydrogen is a good energy carrier, its addition to hydrocarbons could be a good way for the introduction of renewable energies.
In this work, we focus on the effect of hydrogen on two turbulent diffusion flames methane.
The first flame is obtained with a burner coaxial configuration were the jet of fuel is in the center. The second flame is produced by a coaxial burner with a pilot flame. The role of the pilot flame is to maintain the flame. For the first configuration we compared the performance of three turbulence models (the standard k-ε, the RSM model and the modified k-ε) and the performance of two detailed kinetic schemes, the GRI 2.11 and the GRI 3. We do vary the volumetric fraction of hydrogen from 0 to 50% for this flame. Attention was given, here, to the hydrogen effect on the flame structure, the heat power produced, as well as to the effect on the production of polluting gases such as nitric oxide and carbon monoxide.
For second case, we simultaneously vary the initial temperature, the ambient pressure and the hydrogen fraction. The initial temperature is varied from 290 to 600 K, the pressure of 1 to 10 atm and hydrogen volumetric fraction of hydrogen from 10 to 30%.
We have noted that the addition of hydrogen in both cases causes a reduction of the radial and axial expansion of the flame with reduction of the reaction zone; It also causes an increase of the combustion temperature, which induced an increase in nitric oxide emissions.
The increase in pressure causes a narrowing of the flame and reduces the effect of hydrogen.
Finally, increasing the initial temperature causes an increase in the fuel consumption rate.Diplôme : Doctorat en sciences En ligne : ../theses/physique/ZIA7144.pdf Format de la ressource électronique : Permalink : https://bu.umc.edu.dz/md/index.php?lvl=notice_display&id=10458 Etude parametrique de la combustion du methane enrichi a l’hydrogene [texte imprimé] / Lotfi Ziani, Auteur ; Abla Chaker, Directeur de thèse . - [S.l.] : جامعة الإخوة منتوري قسنطينة, 2017 . - 148 f. ; 30 cm.
