  7. Abstract:
  8. Thermo-acoustic sience is the conversion of heat to power through the sound wave. Thermoacoustic engines for different reasons like easy making, not having moving parts and so high reliablibility of system is in attention for researchers. Also looped-tube thermoacoustic engines are very new in the world and sience and thechnology of them belong to a few companies and for different reasons are replacing different kinds of thermoacoustic engines.They have higher efficiency than other types. They can be made in large scales. They have a larger thermal range. In this research, the numerical study of one, two and four stage looped-tube thermoacoustic engines has investigated with the help of DeltaEC software and the validation has been made on looped-tube thermo-acoustic engine and refrigerator combination. One of the most important applications of the multi-stage thermoacoustic engine is the low thermal-difference operation with the help of existing tools: for example, low pressures and use of air as working gas for the use of waste energy in rural and inaccessible areas which does not have the potential to use urban electricity that has been investigated in this research
