Researches for suitable parameters for a project based on "Thermoacoustics" and "Solar Energy" by University of Damascus, software's were developed to be the core for sizing Thermoacoustic devices "Cooler and Prime mover", included the modeling equations of designation. Design strategies were developed. The usage of low technology especially in stack fabrication, as well as to achieve building large sized tunnel that may be used in air conditioning based on solar prime mover is possible. In this paper, parameters of designation were studied to find the impact of affecting temperature gradient over the stack and the desired resonator diameter as a function of temperature gradient and mean pressure when it is prime mover. Some parameters like the heating capacity, and stack spacing were chosen to fit the needs, fabrication, and simplicity requirements. The developed designation resonator diameters were included.
