САЖЕТАК / ABSTRACT:
This paper presents an experimental study on the flame dynamics and radiation properties of small-scale methane fires, with a focus on safety implications in laboratory settings. The experiments were conducted using a methane sand burner to simulate various heat release rates (HRR) ranging from 3 kW to 10 kW. Key parameters, such as flame height and total heat flux, were measured and compared with estimations derived from the Heskestad and McCaffrey models. The results demonstrated good agreement between the experimental measurements and model predictions up to 8 kW, with significant discrepancies arising beyond this point. The study also highlights the nonlinear relationship between HRR and measured incident total heat flux, with the largest increases observed between 3–5 kW and 7–8 kW. The findings should be interpreted with caution due to external influences, such as flame tilting caused by minor airflow in the laboratory. Obtained results provide valuable insights for assessing fire hazards in small-scale methane fires and improving safety protocols.
