A mathematical model based on thermodynamic theory of variable mass is developed for the split Stirling refrigerator, in which, the whole machine is considered by one-dimensional approach while the processes in the regenerator are simulated by two-dimensional approach. First, the influence of the ideal frost layer distributions on the flow and heat transfer in the regenerator and the performance of...
Two-dimensional numerical simulation of thermo-acoustic refrigerator driven at large amplitude is carried out in this paper. Computation of the parameters is based on a pressure-correction algorithm for compressible flows, removing the limitations of traditional simplified linear model of the thermo-acoustic systems. Firstly, the numerical algorithm is applied to an acoustic resonance chamber. The...
