Transient-heat transfer gage measures the total radiation intensity from vacuum ultraviolet and ionized high temperature gases. The gage includes a sensitive piezoelectric crystal that is completely isolated from any ionized flow and vacuum ultraviolet irradiation.
Study reveals quantitative measurements of the diffusion of trace gases /Freon and helium/ injected into systems by different methods. Results show that uniform mixing does not always occur, thus evaluation of the system under test and establishment of the method of trace gas injection are mandatory.
Empirical relations are used for correlating laminar and turbulent friction coefficients for gases, with large variations in the physical properties, flowing through smooth tubes. These relations have been used to correlate friction coefficients for hydrogen, helium, nitrogen, carbon dioxide and air.
Handbook guides selection of construction materials for liquids and gases used in rockets and spacecraft. Methods of design, fabrication, post-fabrication treatment, nondestructive testing, and repair are described in detail.
