Abstract: Excellent indoor air quality in an enclosed area has always become a major safety aspect in designing a building. Issues with regards to circulation of air and exhaust system must be first resolved before the said building can be used for any purposes. The goal of this study is to identify ways to improve air quality in the aviation fire test room at the Propulsion Laboratory that is located in Universiti Putra Malaysia (UPM), Selangor, Malaysia. A computational fluid dynamics (CFD) method was employed to predict the air contaminant inside the lab. When performing the activities, the indoor air quality have to be ensure circulated and ventilated in the lab. Using a mechanical fans and natural ventilation are a traditional method to provide indoor air quality into the propulsion. Whereby, this method may not be enough to provide the required indoor air quality for specific aviation fire-test setup. Such labs may suffer from increasing air contaminant based on the improper and irregular air distribution. A grid independent test (GIT) was done to reduce the effects of meshing on the results was carried out to estimate the discretization error. Computational fluid dynamic (CFD) method was carried out to identify a suitable ventilation system that would result in the greatest improvement in the indoor air quality (IAQ) inside the lab. The results of using the CFD simulation show that installing Local Exhaust Ventilation (LEV) at the lab could significantly improve the IAQ inside the lab. The airflow increase by 84% and the CO, CO2 and NO reduce by 84%, 89 and 81%, respectively. Improvement of the IAQ by increasing the airflow and reducing in the air CO, CO2, and NO, which can be considered as very significant achievement.

Abstract: As the global search for new methods to combat global warming and climate change continues, renewable fuels and hydrogen have emerged as saviours for environmentally polluting industries such as aviation. Sustainable aviation is the goal of the aviation industry today. There is increasing interest in achieving carbon-neutral flight to combat global warming. Hydrogen has proven to be a suitable alternative fuel. It is abundant, clean, and produces no carbon emissions, but only water after use, which has the potential to cool the environment. This paper traces the historical growth and future of the aviation and aerospace industry. It examines how hydrogen can be used in the air and on the ground to lower the aviation industry’s impact on the environment. In addition, while aircraft are an essential part of the aviation industry, other support services add to the overall impact on the environment. Hydrogen can be used to fuel the energy needs of these services. However, for hydrogen technology to be accepted and implemented, other issues such as government policy, education, and employability must be addressed. Improvement in the performance and emissions of hydrogen as an alternative energy and fuel has grown in the last decade. However, other issues such as the storage and cost and the entire value chain require significant work for hydrogen to be implemented. The international community’s alternative renewable energy and hydrogen roadmaps can provide a long-term blueprint for developing the alternative energy industry. This will inform the private and public sectors so that the industry can adjust its plan accordingly.
