| 520 | 3 | ⊔ | ‡aA study is made of the advantages that can be realized in compressible-flow research by employing a substitute heavy gas in place of air. Heavy gases considered in previous investigations are either toxic, chemically active, or (as in the case of the Freons) have a ratio of specific heats greatly different from air. The present report is based on the idea that by properly mixing a heavy monatomic gas with a suitable heavy polyatomic gas, it is possible to obtain a heavy gas mixture which has the correct ratio of specific heats and which is nontoxic, nonflammable, thermally stable, chemically inert, and comprsed of commercially available components. |
