dc.description.abstractThis thesis aims to explore and improve the pneumatic powder delivery system for Laser Metal Deposition (LMD), an essential technology in additive manufacturing. The research is guided by three primary objectives: to analyze the structure of the system, investigate the effects of process parameters, and evaluate potential improvements, both in sustainability and capabilities. A review of existing simulation models and experimental techniques was conducted to identify the most suitable methods for this study. Through a combination of multiphase simulations and high-speed imaging, the research delves into the flow phenomena within the system. Additionally, the powder delivery system of LMD was examined using both simulations and experimental validation. The results reveal significant enhancements in our understanding of the system, offering key insights into the behavior of powder particles during the LMD process. Furthermore, the study identifies areas for sustainability improvements, aligning with the Sustainable Development Goals (SDGs). These findings contribute to the broader field of additive manufacturing by providing a robust framework for optimizing LMD processes and promoting sustainable practices.
