The sulphur boiler furnace used in phosphate industries usually contains three baffles. Their role is to guide the fluid flow inside the combustion chamber. So, they are useful to enhance a complete reaction. The present work shows a numerically investigation of the effect of increasing the baffles dimension on the combustion reaction that occurs inside a sulphur burner. The simulations are performed using the commercial software Ansys Fluent 16.2. A non-premixed combustion model is carried out. The fluid characteristics such as temperature, velocity and mixture fraction are presented

The wilaya of El Oued (southeastern Algeria) suffers from a huge lack of drinking water, unfortunately the groundwater is sometimes too salty for them considered drinking water. The most economical way to obtain drinking water is solar distillation using free, renewable and non-polluting energy. Improvement of the single-slope solar distiller is a problem addressed by several researchers around the world. This study also aims at this point by the variation of the thickness of the glass (the condenser). Experiments show that the production is better improved when the thickness of the glazing is low e = 3 mm with a total production of 2313.2 ml /m2.d; when e = 5 mm the production is 1876 ml / m2.d and at the end when e = 6 mm the production is 1236 ml / m2.d. From these results can be said that any increase in thickness will be followed by a decrease in the productivity of distilled water.

Solar chimney power plants are passive thermal systems that use greenhouse effect to produce electricity from the solar radiations. The performance of these devices vary from one climate to another. Indeed, the building site of the SCPP is a special parameter for its total effectiveness. The aim of this work was to present an experimental investigation of a solar chimney prototype under the climatic conditions of Sfax, Tunisia. In fact, Sfax is characterized by its arid and sunny climate. The impact of the climatic conditions of Sfax city on the aero-thermal characteristics of the considered prototype is carried out. The present outcomes show that the solar chimney power plant is an applicable device in Tunisian region Sfax.

The CFD tool is an important tool to facilate the study of HVAC system. Using this tool, this work involves testing the effect of inlet opening number to follow it impact on the temperature distribution. This numerical study was developed using ANSYS Fluent 17 . The numerical results given by the software proves that the room is colder with eight inlet opening.
Pore scale flow modeling in Silica aerogel using scanning electron microscopy (SEM) image

Image-based pore scale modeling is a powerful computational tool for investigating transport in porous materials. The following is a finite element Stokes flow simulation of a Newtonian fluids through an advanced nanoporous material which is the Silica Aerogel. This type of non conventional pore scale modeling with COMSOL Multiphysics sheds new light on the movement of large particulates and colloids moving through the nanoporous geometries.
