In this study cross section geometry and material of gasket in proton exchange membrane (PEM) fuel cells have been investigated to achieve optimized fuel cell in terms of energy efficiency. The role of gaskets in fuel cells is sealing of gas flow channels and preventing from combination of them. In a PEM stack, gasket with approved geometry that suffers more stress has better sealing. For this ...

The present work has developed a methodology for studying natural ventilation in Mediterranean greenhouses by means of sonic anemometry. In addition, specific calculation programmes have been designed to enable processing and analysis of the data recorded during the experiments. Sonic anemometry allows us to study the direction of the airflow at all the greenhouse vents. Knowing through which v...

In recent years, natural ventilation technology is extensively used in order to improve indoor environment quality and reduce power consumption of air-conditioning systems in green buildings. However, the effect of natural ventilation on fires needs to be evaluated carefully, and how to make these energy-saving buildings safe is a topic worth studying. This study uses Fire Dynamics Simulator on...
