摘要
应用低温风洞模拟热喷流,是喷流模拟技术一大进步。本文讨论了喷流模拟相似参数,分析了现有冷喷和热喷技术不足,指出应用低温风洞模拟喷流的基本优点,研究表明,通过选择不同组成和组分的喷流模拟气,低温风洞可实现喷流全参数完全模拟。
It's an important advance for jet simulation to simulate hot jet by cryogenic wind tunnels. In this paper, concerned similarity parameters for hot jet simulation are discussed, disadvantages of available cold jet and hot jet simulation techniques are studied and essential merits of hot jet simulation by cryogenic wind tunnels are indicated. Examination shows that cryogenic wind tunnels may perform full-parameter simulation for hot jet by choosing gas mixtures with different components and mole fractions.
