Computational Study of Turbulence and Recirculation Effects in Turbine Blade Cooling Channel
This study introduces a two-dimensional computational model for the cooling passages in turbine blades. Turbulators are installed on both sides of the duct to enhance turbulence and improve heat transfer efficiency. The objective of this research is to analyze rectangular turbulators by examining the velocity, pressure, and turbulence before and after the turbulators. The findings reveal that recirculation zones diminish following the first two turbulators but increase behind the final turbulator upstream of the U-turn. Significant recirculation occurs on the upper and outer sides of the bend. High-velocity regions are observed on the inner side of the bend and after the first lower turbulator downstream of the U-turn.
Preparedness Firefighter for Electric Vehicle Accidents: A Comparative Analysis between Kuwait and European Countries
This study presents a comprehensive analysis of the preparedness and knowledge of firefighters in Kuwait regarding electric vehicle (EV) accidents. Using a multi-method approach that includes surveys, literature reviews, statistical data, and interviews with emergency responders and municipal officials in Sweden, the study compares EV preparedness in Kuwait with that in selected European countries (Norway, Iceland, and Sweden). The findings reveal significant gaps in training and knowledge among Kuwait firefighters, indicating an urgent need for enhanced training programs and standardized protocols. Best practices from European countries, such as specialized training programs and advanced detection equipment, are highlighted as potential solutions for improving safety and preparedness in Kuwait. The study aims to enhance readiness for the increasing adoption of EVs, ensuring the safety of responders and the public. Key recommendations include the development of comprehensive training programs, establishment of standardized protocols, investment in specialized equipment, and fostering international collaboration. Future research directions are also suggested to further improve EV accident management.
