Low temperature difference thermoacoustic prime mover with asymmetric multi-stage loop configuration

Abstract Environmentally friendly and low-cost technologies to recover low-grade heat source into usable energy can contribute to ease the energy shortage. Thermoacoustic technology is expected as one promising approach in this ascendant field. In this work, the multi-stage looped thermoacoustic pri...
