Parametric evaluation of heat transfer mechanisms in a WUI fire scenario

Background Wildland–urban interface (WUI) fires are becoming more frequent and catastrophic as they associated with the effects of climate change, demographic pressure, human activities, abandonment rural areas activities promoting dangerous fuel continuity. For example, in central regions Portugal, Chile California, severe direct indirect impacts have been observed, a number fatalities.Aims Mitigating reducing wildfires WUI requires understanding heat transfer mechanisms from forest how structures ignite is crucial to define implement new mitigation strategies.Methods Adopting Computational Fluid Dynamics essential assess fire problem by simulating behaviour quantifying its characteristics. In this paper, building exposed several wildfire scenarios, assessing influence parameters such materials, fuels, topography meteorological conditions.Key results The investigated scenarios were developed considering validated Fire Simulator (FDS) models single trees on governing was quantified.Conclusions selected assessed compared, release rates, radiative flux adiabatic surface temperature.Implications This research contributes Performance-Based Design (PBD) approach for buildings WUI.
