Abstract

The thermoacoustic conversion system is designed, while the position and structure parameter of stack are calculated and analysed. At the same time, the parameters of stack and the input working frequency which influence the system are researched by experiment. The results show that the center position of stack in the standing-wave tube and the length of stack have great influence on the system, and exists a best value in the same input power and frequency; Meanwhile, the pore diameter and wall thickness of stack are also exist the best values, the temperature difference at both ends of stack will be reduced if the value is too big or too small; The best working frequency of the system is migrated due to the stack, working fluid and so on.
