A technique is developed to measure burning velocity using soap bubbles and a hot-wire anemometer. This method is a modified version of that mode by Andrews and Bradley. The principle of this method is the simultaneous measurement of flame speed and unburned gas velocity ahead of the flame in a soap bubble. The flame propagation is recorded using a schlieren system with chopped light source. The method has been used to measure the burning velocity of methane-air mixtures over a wide range of equivalence ratios. This method gives a maximum burning velocity of 45 cm/s, at an equivalence ratio of 1.08. Values of burning velocity determined in this way are in good agreement with those of Andrews and Bradley and those of other accurate methods, but in moderately rich mixtures, the present data are slightly higher than those obtained by other workers using burner methods. The influence of flame curvature upon the burning velocity is discussed.
