首先对气波增压器的设计方法进行了探索，提出了基于一维非定常定熵流动的简化图解法和基于一维非定常非定熵流动的数值解法。然后在原有的欧拉法基础上又提出了欧拉／拉格朗日混合解法。加工了大、中、小三个不同尺寸的气波增压器，进行了实验研究，找出了影响性能的几个主要因素。最后得出三个气波增压器较佳的性能数据，为匹配不同功率的中小型柴油机提供一种新型增压装置。 Firstly, the design method of gas turbocharger was explored. A simplified graph based on one-dimensional unsteady entropy flow and a numerical solution based on one-dimensional unsteady unsteady flow were proposed. Then based on the original Euler law, Euler / Lagrange hybrid solution was proposed. The processing of large, medium and small three different sizes of gas turbocharger, conducted an experimental study to identify the impact of performance of several major factors. Finally, three gas turbochargers are given better performance data to provide a new type of supercharger for small and medium-sized diesel engines with different power.
