Abstract
- For the stack of the standing-wave thermoacoustic refrigerator, the essential features of the time-averaged heat flux density distributions inside a thermally isolated thermoacoustic stack were theoretically studied. The analytical formulation of the accurate mean temperature difference ΔT<subscript>m</subscript> was achieved. In comparison with experimental results and linearization results, the derived formula to calculate the mean temperature difference ΔT<subscript>m</subscript> was proved to be correct. The position and characteristic parameters of stack for the standing-wave thermoacoustic refrigerator could be optimized with the use of analytical formulae obtained as follows. The optimal position of stack is x<subscript>s</subscript> = f<superscript>-1</superscript> (ΔT<subscript>m</subscript>), optimal plate distance is 2y<subscript>0</subscript>/δ<subscript>κ</subscript> = 3.3~3.4 and the plate thickness is 2l/δ = 0.7.
