Heat Flux From Flames to Vertical Surfaces



J. G. Quintiere, Thomas Cleary


Dimensional analysis is used to examine heat transfer from flames to vertical surfaces. Configurations include a line fire against a wall, a square burner flame against a wall and in a corner, and window flames impinging on a wall. Dimensionless parameters that affect flame heat flux include [equation] where x is vertical distance, y is horizontal distance, l is flame length, D is burner dimension, and k is the flame absorption coefficient. Only the effect of these variables is shown. No general correlation is developed, and more data are needed before these results can be applied with confidence.
