Abstract
The process of the spread of flames over the surface of a flat combustible material forming a vertical wall-horizontal ceiling corner has been studied experimentally. The rates at which flames spread over the wall and ceiling surfaces ae measured as a function of the wall height and ceiling length. It is found that for PMMA as combustible material, and for the present scale of the experiments, the upward flame spread rate is practically independent of the ceiling wall length. However, the rate of spread over the ceiling wall is considerably influenced by the height of the vertical wall. This height affects the time of initiation of the spread of the flames over the ceiling surface and the dependence on time of the rate of spread.
