معرفی
Dr. Alexander Belt is a researcher at the Research Center Jülich GmbH, specifically within the Institute for Advanced Simulation (IAS) and its Civil Safety Research (IAS-7) division. His work focuses on fire safety engineering and visibility analysis in compartment fires.
His research investigates smoke propagation, toxicity, and visibility prediction using computational fluid dynamics (CFD) models like the Fire Dynamics Simulator (FDS). Key methodologies include photometric measurement techniques (LEDEX, MIREX), particle image velocimetry (PIV), and electronic low-pressure impactor (ELPI) for particle size analysis. Publications highlight experimental-numerical model discrepancies in visibility prediction and development of improved measurement frameworks.
Recent work includes a waypoint-based visibility approach in fire safety design (2024), tube furnace experiments for pyrolysis analysis (2024), and aerosol extinction coefficient modeling (2024). Collaborative publications with Lukas Arnold, Thorsten Schulze, and others demonstrate interdisciplinary safety research.
