摘要
基于气体动力学原理,由数学模型得出气流一元流动的特性:流速与压力的关系、流速与断面的关系,并分析说明原因。然后根据理论用软件进行数值模拟,结果与理论相符合。
Based on theory of gas dynamics, the paper gets gas unitary flow characteristics from maths model and analyzes the cause. The characteristics include the relation of gas velocity, pressure and cross section. According to analysis, digital simulation is made by software. The results are identical with the theories.
