Do it yourself: make your own thermoacoustic engine with steel wool or rice

Abstract

The construction of two demonstrators of thermoacoustic engines is proposed in this paper, using common material from hardware stores. A brief discussion about the thermoacoustic effect highlights the main parameters controlling the generation of self-sustained acoustic oscillations from heat. The construction of the two tabletop demonstrators is then described in detail, so that they can be reproduced with minimum equipment (rice, steel wool, and other hardware easy to find in hardware stores). Experimental results are also presented for both engines and a discussion about their use for teaching purposes is provided.
