In the first simulation by DeltaE, the blockage ratio of the heat exchangers is assumed equal to that of the stack. The porosity of the heat exchangers is optimized through the second law analysis and by assuming the plate thickness of the heat exchangers equal to their length. The optimized blockage ratio for the cold heat exchanger and ambient heat exchanger are estimated 0.56 and 0.345. The results show that with the optimized heat exchangers whose porosity is less than that of the stack, the overall performance of the thermoacoustic refrigerator is increased by 16%.}, number={3}, journal={Canadian Acoustics}, author={Babaei, Hadi and Siddiqui, Kamran}, year={2007}, month={Sep.}, pages={170–171} }
