Summary
Net heat flux into the painted floor object of the worked example (convective coefficient assumed at 25 W/(m²·K)) against its surface temperature; the flux becomes zero at the adiabatic surface temperature of about 377 °C. Based on McGrattan et al. (2026), pp. 77–79, and Van Rossum (2027), §4.7.
Original illustration for Adiabatic surface temperature, level 4 Expert.
- Source basis: McGrattan et al. (2026), pp. 77–79 (heat balance); Van Rossum (2027), §4.7 (20 kW/m²), §5.2 (hc 20–25 W/(m²·K) for a fully developed fire, 25 for a standard fire; assumed), §5.4 (σ, emissivity)
- Alt text: Line chart: net heat flux into the floor object falls from 17.6 kW/m² at 20 °C to zero at 377 °C, the adiabatic surface temperature.
