本文先简述气波机的发展史,然后讨论用这种气波机作燃气透平前置级所出现的热力学和结构问题。通过大量算例,包括对设备费用的估计,作出了经济上的展望。结果表明,它存在着可观的发展潜力,特别是它能大幅度提高比功率。适于达到这一目的的机械型式是压强变换器和压强交换器。对用作燃气透平前置级的气波机的要求与目前已实现的气波机(例如用作内燃机的增压)相比还相距甚远。看来有必要制定一个独立的广泛的研究计划,而将现有的研制量集中到一直在快速发展的简单的燃气透平上。
This article first briefly describes the history of gas wave machines and then discusses the thermodynamic and structural problems that arise with this gas wave machine as a pre-gas turbine stage. Through a large number of examples, including the estimated cost of equipment, made an economic outlook. The results show that it has considerable potential for growth, in particular that it can significantly increase specific power. The types of machinery that are suitable for this purpose are pressure transducers and pressure exchangers. The requirements for a gas wave machine used as a gas turbine pre-stage are far from what has been achieved so far for gas wave machines, for example for supercharging of internal combustion engines. It seems that there is a need to devise an independent and extensive research program and to focus the current research efforts on the simple gas turbine that has been rapidly evolving.
