    Critical point measurements on nearly polydisperse fluids (1984)

    Notes: The critical temperatures, pressures and volumes of several mixtures containing CO2, C2H6, C3H8, and C4H10 have been measured using a heavy walled, variable volume, cylindrical glass vessel. In each mixturre the relative proportions of the three hydrocarbon solutes to one another were changed; total solute mole fraction never exceeded 0.1. A detailed study of the mixture CO2 + C3H8 shows that the critical temperature exhibits a minimum at a C3H8 mole fraction of 0.0265. Our mixture data are analyzed using a polydisperse model of dilute solutions.

    Digital image analysis of isoelectric focusing patterns (1984)
    Weinheim : Wiley-Blackwell
    Electrophoresis 5 (1984), S. 55-56

    ISSN: 0173-0835

    Notes: In a study of intersterility groups in the genus Armillaria, a scanning stage microscope photometer was used to obtain digitized images of photographs of isoelectric focusing patterns. Absorbance values were then mapped from the metric scale to the pH scale. Absorbance values in specified pH intervals were used as features in multivariate statistical procedures to characterize populations and to assign isolates to populations. Digital image analysis techniques were used to obtain an enhanced image of faint or poorly resolved bands.

    Phase average measurements of the coherent structure in a Mach number 0.6 jet (1984)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: Phase averaged measurements of the axial mass velocity, radial velocity, and the product of the two have been made in an artificially excited cold air jet. The radial velocity fluctuations had a lower amplitude for both the full wave and phase averaged fluctuations compared to the axial mass velocity fluctuations. The Reynolds stress tended to decay faster in amplitude than the axial mass velocity and radial velocity fluctuations for both the full wave and phase averaged components. The radial velocity fluctuations possessed higher levels of coherence than the axial mass velocity fluctuation and the Reynolds stress. When the jet was excited at the frequency of St = 0.474, a high amplitude component at that frequency dominated the entire phase averaged flowfield from X/D = 1 to 10. This fundamental frequency was accompanied by several relatively high amplitude harmonics. These harmonics were more pronounced in the radial velocity fluctuations than for the axial fluctuations or the Reynolds stress.

    Frequency dependence of coherent structures in a Mach number 0.6 jet (1984)
    In:  Other Sources

    Publication Date: 2019-06-28
    Description: The existence of a large scale structure in a Mach number 0.6, axisymmetric jet of cold air has been proven by previous work. In order to further characterize the coherent structure, phase averaged measurements of the axial mass velocity, radial velocity, and one component of the Reynolds stress tensor were made. These measured values were compared to the total fluctuation levels for each quantity and the result expressed as a percent of the total fluctuation level contained in the organized structure at Strouhal numbers of 0.16, 0.32, 0.474, 0.95, and 1.26. All of the phase averaged measurements required that the jet be artificially excited. The fluctuation profiles showed that the axial mass velocity fluctuations maximized when excited at a Strouhal number of 0.474. The radial velocity fluctuations possessed a lower amplitude for both the full wave and phase averaged fluctuations than the axial mass velocity fluctuation. The Reynolds stress decayed faster than the other two quantities past the end of the potential core for both the full wave and phase averaged components. The coherence contours showed that the radial velocity fluctuations possessed higher levels of coherence than the axial mass velocity fluctuation and the Reynolds stress.
