Solar radiation prediction is essential for several research applications in renewable energy. In particular, solar irradiation can be considered as a target parameter related to greenhouse microclimate. This study developed a model based on an artificial neural network (ANN) for predicting incident solar radiation on a horizontal surface in an agr...

This article aims to investigate the impact of regular openings in L-shaped reinforced concrete (RC) shear walls located at building corners. A comparison of different buildings and an estimation of the optimal percentage of openings were conducted. To accomplish this, various wall models, with and without openings, underwent numerical simulations...

This article contributes to deepening our understanding of the distribution of compression, tension, and shear stress in reinforced concrete mid-rise building shear walls. These L-shaped shear walls include openings that can account for up to 50% of the total wall area. To conduct this study, seismic performance analyses of the buildings were carri...

As an example of green energy (geothermal energy), which has been the subject of advanced research in recent decades, the earth-to-air heat exchanger (EAHE) is the application of an air heat exchanger to soil temperatures, in which air circulates in tubes in thermal contact with the ground. The performance of the EAHE cooling system is evaluated at...
Article
Among the renewable energies, there is geothermal energy, conventional air conditioning has negative consequences on the environment, to have an economical and sustainable solution: the EAHE respond to this concern. In the current study, the study of the thermal performance of the earth-air heat exchanger (EAHE) has been completed. For the impact o...

Building aeration ventilation may contribute to achieve thermal comfort there by economizing huge amount of electricity that would be supplied using conventional air conditioning systems. Natural ventilation maintains thermal equilibrium between heating and cooling balances. They may also be used in conjunction with other systems in certain circums...
Article
In order to reduce fossil energy consumption at desalination plants, it has become necessary to replace fossil energy with clean energy. Currently, the reverse osmosis systems connected to solar energy is a promising technology for desalination of seawater / brackish water, especially in arid and semi-arid areas that have a large solar deposit and...

In this work, we propose to experimentally and numerically study the natural convection in laminar regime in an agricultural greenhouse located in South West of Algeria and more precisely in the Adrar area. The numerical study is two-dimensional and was carried out on a tunnel greenhouse with an area of 180m2 located in Adrar in the southwest of Al...
Article
An attempt is conducted in this paper to develop an artificial neural network (ANN) model for predicting the efficiency of small-scale NF/RO seawater desalination, then applied to the simulation of permeate flow rate and water recovery. A feed-forward back-propagation neural network with the Levenberg-Marquardt learning algorithm is considered. The...

Greenhouses need energy to create a suitable climate for crop production in winter period. Renewable energy seems to be the appropriate and sustainable energy source to heat greenhouses. The aim of this work is to investigate the possibilities of improving the inner greenhouse climate using sensible heat storage material. A comparative study was co...
Article
The Mediterranean area is characterized by intense radiation generating high temperatures during the day in the greenhouse and low temperatures during the night. The temperature gap problem between the daytime and the nocturnal period which characterizes the region requires the use of greenhouses with a thermal storage system. A greenhouse equipped...
Article
Some models of the artificial neural network (ANN) are introduced in the control system of a Nanofiltration / Reverse Osmosis desalination in order to manage the operation and to improve the overall efficiency. This study is carried out on a small-scale prototype of NF/RO seawater desalinate++on plant installed in Saudi Arabia and allowing it to op...

This work consists to study the storage system effect on thermal performance of an agricultural greenhouse in semi-arid climate case Ghardaia. The data climate is used for predict the energy needs as comparison with another without storage system. The obtained results indicate that the outside needs are less than the not heated with 3 to 5°C during...

L'utilisation des serres solaires dans le domaine de la production agricole s’est multipliée ces dernières décennies. L’objectif principal d'une serre est de produire un rendement plus élevé en dehors de la saison de culture, ce qui est possible par le maintien de la température optimale à chaque étape de la culture. Un système de chauffage appropr...

In this paper a mathematical model of sensible heat storage in a rock bed used in a tunnel greenhouse is presented. A computer program based on MATLAB software has been used to predict the time evolution of the temperature. The numerical results show that the heat storage system is mainly affected by the diameter of the rocks ( rocks size ), convec...

The performance of solar conversion systems is affected by its orientation and tilt angle with the horizontal plane. This is because both of these parameters change the amount of solar energy received by the collector surfaces. In this study, the optimum tilt angle of solar systems is determined in order to increase the solar radiation amount reach...
