...Shohel Mahmud; Roydon Andrew Fraser The problem of therporacoustic (thermal-porous-acoustic) convection near a porous medium, representative of a stack in a thermoacoustic engine/refrigerator, is modeled and analyzed in this paper. Assumptions (e.g., long wave, short stack, and small amplitude...

... only half the Carnot value. The power dissipated in the regenerator is removed as part of the heat withdrawn at the regenerator’s cold side. Analogous results are presented for the Stirling refrigerator. At optimized nondimensional rate of refrigeration, its coefficient of performance is less than half...

...K. Pavan Kumar; G. Venkatarathnam Matrix heat exchangers are used in a number of applications such as helium liquefiers, sorption refrigerators, and in Kleemenko cryocoolers. In this paper the methods for the optimum sizing of balanced flow and unbalanced flow matrix heat exchangers of rectangular...
