Abstract:
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.
