Abstract
This paper describes two complementary investigations into the factors affecting the pressure loss across flame-stabilizing baffles. In the first a series of tests made under ‘cold’ and burning conditions is reported, and it was found that except when very high rates of heat release were utilized, observations made in the cold and burning tests were compatible. It was suggested that the large increases in loss observed in certain cases were due to the effects of flow pulsations. The second investigation, made under more controlled conditions, confims this, and a simple quasi-steady theory of the effects of the pressure fluctuations is found to account wholly for the results obtained.
