摘要:
热声换热器热量传递的速率与效率直接影响着热声热机的性能.   耗散理论能更好地揭示换热器的传热优化特性,在热声换热器研究中引入  耗散理论,针对顺流和逆流两种情况,计算了热声换热器的  耗散热阻,并和最小熵产原理的结果进行了对比分析. 结果表明,在一定条件下,顺流比逆流情况下的不可逆损失要大;当换热器低温端流体的热容量小于高温端流体热容量时不可逆损失较小,结果最优.
Abstract:
The rate and efficiency of heat transfer in the thermoacoustic heat exchanger affect the performance of the thermoacoustic engine. The entransy dissipation theory was adopted in the study because it can better reflect the performance of heat exchanger. The entransy dissipation resistance of the thermoacoustic heat exchanger was calculated in the conditions of the parallel-flow and the counter-flow, and was compared with that of the minimum entropy generation principle. The study shows that the irreversible resistance in the parallel-flow is larger than that in the counter-flow. The irreversible resistance is the smallest and the result is the best when the heat capacity at the low temperature end is less than that at the high temperature end in the thermoacoustic heat exchanger.
