  • An experimental investigation of aerosol coagulation in the shock tube

    Creator:
    Yun, Kyung Woo
    Abstract:
    Ammonium chloride aerosols of submicron size generated by condensation and dispersion methods were treated, shortly after aerosol charging, with shock waves originating from diaphragm pressure ratios of up to 5.75. The fraction of the particulate matter remaining in suspension after a given time was measured as an indication of coagulation...

  • Integrated forward light scattering as a measure of aerosol mass concentration

    Creator:
    Tomine, Chris Shinya
    Abstract:
    A mathematical model was developed that relates the ratio, R, of two light flux measurements to the mass concentration, m, of the atmospheric aerosol particles between a source of parallel light (e.g., the sun) and the measuring system. R is defined as the ratio of the light fluxes passing through...

  • Sampling submicrometer particles suspended in near sonic and supersonic free jets of air

    Creator:
    Martone, Joseph Arthur
    Abstract:
    This experiment is concerned with sampling submicrometer particles in near sonic and supersonic flows. The study employed a high volume condensation aerosol generator to produce stearic acid particles having a geometric mean diameter of 0.8 μm and a geometric standard deviation of 1.28. The aerosol was diluted with dry air...
