This book was released on 1966 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods of experimentally determining the transport properties of high temperature gases have been developed and measurements of viscosity, thermal conducitvity, and diffusion coefficients obtained. The heat transfer rate through laminar boundary layers, the absorption of sound, and a schlieren method have been investigated for the determination of transport properties. Heat transfer measurements on the side wall of the shock tube have been used to obtain viscosities of argon, oxygen, nitrogen, and carbon dioxide up to 4000 K. The boundary layer equations were solved for side wall boundary layers in the shock tube in oxygen to assess the relative importance of viscosity and thermal conductivity in heat transfer to the side wall. Thermal conductivities were deduced from end wall heat transfer measurements in carbon dioxide up to 2000 K and oxygen up to 4000 K. End wall heat transfer measurements in nitrogen and argon have been compared to theory with excellent agreement. Various methods for measuring ultrasonic absorption are discussed. The viscosity of argon at temperatures up to 8000 K were determined with the ultrasonic method. Diffusion coefficient in 50-50 He-Ar mixtures have also been obtained from the ultrasonic measurements at room temperature with excellent agreement with other investigators. The theory of a schlieren method for the measurement of thermal conductivity using the end wall boundary layer in the shock tube is discussed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Methods of experimentally determining the transport properties of high temperature gases are discussed. A constant area helium driven shock tube is used as the high temperature gas source. The two methods presently under investigation are heat transfer and ultrasonic. Heat transfer rate measurements have been obtained in argon, nitrogen, and oxygen for temperatures up to 8000 K. Preliminary thermal conductivity data are presented for oxygen for temperatures up to 4000 K. The ultrasonic method has been used in determining temperatures of shock heated argon (up to 9000 K) and nitrogen (up to 3000 K). The extension of the ultrasonic method in determining transport properties of gases at elevated temperatures is indicated. (Author).

This book was released on 1971 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transport property measurements with ultrasonic techniques are discussed over the entire temperature (100-15,000 degrees) and pressure (1-1000 atm) ranges. A chart of various techniques for the determination of transport properties in the various temperature and pressure ranges is given. Sound absorption and sound speed determinations were used to obtain thermophysical properties of argon, helium, nitrogen and air at room temperature and pressures between 1-500 atm. Several variations of pulsed ultrasonic techniques were used to obtain maximum precision in the gas property measurements. Sound speeds accurate to approximately 0.1% were obtained in all the gases. Thermal conductivity and specific heat ratios were deduced for air. A cavity technique was developed for high accuracy (

Available in PDF, EPUB and Kindle. Book excerpt: A new technique for the accurate (1-0.01%) determination of transport and thermodynamic properties of gases is described. This technique consists of measuring the linewidth of a small acoustic resonator. The linewidth of more than one type of resonance allows the transport properties (thermal conductivity and viscosity) to be determined independently. The center frequency gives the sound speed. The theory of the acoustic resonator is presented including the effects of relaxation in the gas, slip and accommodation on the cavity walls, and acoustic transmission into the walls. The contributions of transducer coupling and feed through are also included in the cavity theory. Realization of cavities and transducers suitable (but not optimized) for measurements at temperatures up to 1000K and pressures up to 500 atm are discussed. Measurements employing the resonator technique are presented in Ar, N2, air and H2. High pressure measurements (p
