摘要: Abstract Theoretical modeling for a microscopic ESE (energy selective electron) heat engine with double-resonance energy filters is performed in this paper. The flow characteristics and performance parameters are discussed two different cases according to the positions central level of double resonances. It found that analytical expressions parameter such as power output or efficiency share identical form. optimal system analyzed by using finite time thermodynamic theory. curves fundamental relation system's explored numerical examples. an open loop-shaped curve. There exist maximum output. operating regions determined influences design discussed. Finally, comparison double- single-resonance carried out order show differences effect newly adopted utilization filter leads increased while decreased electron device.
