An Augmented Reality Application for an Immersive Laboratory Experience: The Zittau Flow Tray

Abstract Integrating augmented reality (AR) into engineering education can enhance the learning experience for complex concepts. This study presents an AR application’s engineering process and prototype for the Zittau Flow Tray using (ZFT) Microsoft HoloLens 2 and Unity 3D. The application provides information on sump recirculation operations after a loss-ofcoolant-accident in pressurized water reactors. Key features include interactive 3D models, flow simulations, and dynamic information overlays. Initial testing validated the application's core functionalities, though challenges such as user positioning accuracy and real-time data integration remain. Future enhancements will focus on refining these aspects and broadening the application’s usability across various AR platforms.
