Abstract
A series of model experiment was conducted for evaluating heat transfer to a non-flammable eave during flame impingement. Excess temperature ΔT and incident heat flux to the eave q″ were measured under sixteen experimental runs with varying parameters of eave section geometry, burner geometry, installation position of the burner, and fuel supply rate. In order to correlate the maximum excess temperature ΔTmax , a reference length scale L was deduced from the governing dimensionless parameter Q*. Dimensional analysis of thermal structure of the flow showed that the maximum excess temperature ΔTmax is expected to be proportional to ((x +H)/L)0 in the flaming regime, and ((x +H)/L)-1 in the non-flaming regime. The agreement with the experimental data was reasonable for all the tested eave sections and burner geometries.
