摘要

利用空气动力学理论，建立高效气波冷凝波图，采用二维周期性边界模型，以理想气体为介质对高效气波冷凝分离装置流场、温度场进行数值模拟，优化气波冷凝波图，预估装置内部结构参数。建立冷凝系统热力循环模型，对其热力学特性进行分析。同时搭建实验平台，对影响系统的主要参数进行了研究。实验结果表明：利用激波增压回收高压气源压力能，可以有效恢复脱湿干气压力能。通过回收脱湿干气冷量，预冷下一循环高压进气，可以获得更低冷凝温度。该装置制冷效率存在单值最优点，高效气波冷凝实际内部膨胀效率约为63%，脱湿干气压力能最高恢复90%，且随着制冷压比增大而降低。

Abstract

With the theory of aerodynamics

the efficient gas wave condensation graph was established. To optimize the gas wave condensation graph and estimate the internal structure parameters of the device

the two-dimensional periodic boundary model was adapted and the ideal gas as the medium was used to numerical simulate the flow and temperature field of the efficient gas wave condensation separator. The thermodynamic model of condensing system was established and its thermodynamic properties were analyzed. At the same time

the experimental platform was built

and the main parameters of the device were studied. The experimental results shows:by using the shock wave to recycle the pressure energy of the high pressure admission

the pressure energy of the drying gas can be highly recovered. By recycling the cooling capacity of the drying gas and pre-cooling the next high pressure admission circulation

the lower condensation temperature can be obtained. The refrigeration efficiency of this device exists the single-valued optimal point. The internal expansion efficiency of efficient gas wave condensation is about 63% and the maximum of the drying gas pressure can be recovered to 90%

which decreases with the increase of the pressure ratio.
