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
In this paper, the numerical results of the study on geothermal-air heat exchanger in dry areas of Algeria (Ghardaia region) were presented. Computational fluid dynamics equations were solved using our specific code compilated with Fortran. The outputs of the numerical calculations were compared and validated with the experimental results and the o...

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...

The crystal structure of bis(4-chloroacetylphenyl)selenide was solved by the direct methods; the refinements of the structural factors were carried out by least squares refinements and covered 190 parameters. The compound crystallizes into Triclinic system with space group P-1 symmetry and Z = 2. At 293 K, the crystal structure parameters are a = 7...

The electronic and ionic effective potential of a fully ionized hydrogen plasma containing an impurity of electric charge (+Zme) are calculated in a two-component plasma model under semiclassical conditions using classical statistical mechanics with a regularized electron–ion interaction. These effective potentials are coupled in a system of nonlin...
