Summary

Heat flux onto and through a wall: radiation from the flame and the smoke layer, convection from hot gases along the surface and conduction through the wall. The heat flux is the heat flow per square metre, in W/m² or kW/m². Based on Van Rossum (2027), §5.1–§5.4.

Source basis: Van Rossum (2027), §5.1 (three mechanisms), §5.2 (q̇″ in W/m², conduction), §5.3 (convection from moving gas to a surface), §5.4 (radiation, view factor)
