Impact of Temperature Gradient on Thermoacoustics Refrigerator

AbstractIn an extended search for suitable parameters of the project base on “Solar thermoacoustic refrigerator” funded by University of Damascus, which has built in the faculty, early softwares were developed to be a core of sizing Thermoacoustic cooler and prime mover, included the modeling equations for designation. Since high technologies were required, it was necessary to change the design strategies in order to allow the usage of low technology especially in stack fabrication, as well as to achieve building large sized tunnel that is used in air conditioning based on solar prime mover. In this paper, the new design strategy were modified to obtain a new software for sizing a Thermoacoustic device that would simply be built manually, in addition to find the impact of affecting temperature gradient over the stack. Some parameters like the heating capacity, cooling capacity, mean pressure, and stack spacing were chosen to fit the needs, fabrication, and simplicity requirements. The optimum temperature gradients were included in this paper
