WebSep 1, 2024 · It compared the thermoacoustic engine to conventional Stirling-cycle heat engines and the pulse-tube refrigerator. Nearly two decades later, Backhaus and Swift were able to execute a Stirling cycle using a traveling-wave engine that had a thermodynamic efficiency equal to that of an internal combustion engine. 4 4. WebThe objective is to obtain a substantial temperature gradient using a Thermoacoustic Refrigerator. The methodology is to choose the suitable material and design the prototype. A large part of this project is devoted to explore the different designs for thermo acoustic refrigerators, and select the optimum one for maximum utility.
