Sensitive Flames — •Adrian Ebert1 and Thomas Grillenbeck1,2 — 1Ignaz-Günther-Gymnasium Rosenheim, Germany — 2Rosenheim University of Applied Sciences, Germany
A combustible gas streams out of a fine nozzle and is lit above a copper mesh at a distance of ca. 5cm. The copper conducts away the heat, thus the flame only burns above the mesh and leaves a space of air underneath it. When an acoustic signal meets the resonance of the flame, delivering a certain amount of energy, the flame reacts very sensitively and changes its shape and size. A fishtail nozzle creates a membrane of fire which, in theory, allows an even easier influence. We examine this phenomenon, in order to spot the influence of various parameters.
