Abstract: Evaporative air coolers are one of the alternatives to conventional air conditioners for cooling the air in the building. These systems consume less energy and contribute to the reduction of greenhouse gases. This work is a numerical study of an evaporative exchanger based on fired clay plates using COMSOL Multiphysics software. It was interested in hygrothermal transfers for air cooling. This study allowed to highlight the impact of the gap between the fired clay plates, the speed of the area as well as the air temperature at the inlet of the exchanger on the evolution of temperature and relative humidity of the air along the fired porous clay plates. The thermal efficiency of the exchanger was subsequently evaluated. This study allowed to note that there is a drop of 14 K along the porous plates of fired clay. Speed has an influence on outlet temperatures and relative humidity. For a speed of 0.2m/s, the temperature variation is 16 K and for speeds ranging from 2 m/s to 4m/s, the temperature variations are approximately 17 K. For gaps in porous plates of fired clay less than 2cm, the thermal efficiency varies 92% to 98%.

Abstract: This study aims to analyze the content of the “Nearpod” application that engages students in interactive learning experiences; where students could participate in virtual reality; Using e-learning websites, tablet applications and smart devices to achieve the best student responses in the field of distance learning to improve the creative writing skills of Grade 10 students in Arabic language. The study targets students of the second stage to identify the availability of the digital elements that make up the application on both writing and reading axes, The study aims to measure effect of the interactive activities in the Nearpod to improve the standards of “Creative writing” which builds students writing skills (Fluency, Originality, Flexibility, Expansion). Based on the results obtained, which showed that the application included interactive activities that could be effectively invested in the design of virtual classes for creative writing in the Arabic language, which depends largely on the teacher’s effort in creating distinguished classes to attract students, monitor their responses, and follow up their interaction and development, The researcher presented a preliminary conception or proposal for the written expression classes and made recommendations regarding the necessity of exploiting the electronic content of the application “Nearpod” in designing the preparatory creative writing classes before the post-test writing.
