    A novel radioactive particle tracking facility for measurement of solids motion in gas fluidized beds (1985)

    Notes: Measurements of solids motion in a fluidized bed have been made in a computer-aided particle tracking facility. A radioactive tracer particle, dynamically identical to the solid particles to be studied, was mixed with the solids in the bed. The gamma radiation from the tracer was continuously monitored by a large number of scintillation detectors located around the bed, providing information on the tracer's instantaneous location. Prudent use was made of the purposely introduced redundant distance data to achieve improved accuracy. The recognition of the existence of secondary emission due to the interaction of the primary radiation and other system materials and the subsequent devising of a scheme to mitigate its effect contribute much to the success. Results for a bed with a uniform air distributor plate show the existence of two counter-rotating toroidal vortices whose relative sizes and strengths vary with the fluidizing velocity. Fluctuating motions at low frequencies ranging from 1.6 to 16 Hz have been observed at various locations in the bed.

    Small angle and wide angle x-ray pole figure studies on simultaneous biaxially stretched poly(ethylene terephthalate) (PET) films (1987)

    Notes: Biaxially oriented poly(ethylene terephthalate) (PET) films have been characterized by small angle and wide angle x-ray scattering. The films were studied at various rotational angles to the impinging beam and orientations relative to axes in three directions in the film were obtained. Pole figures were developed for both the major small angle scattering peak and wide angle diffraction peaks. These are used to interpret structural changes in the films associated with various degrees of biaxial stretching and subsequent constrained annealing.

    Transverse properties of undirectional aluminum matrix fibrous compositesThe editor accepts this paper, although it does not discuss polymers. It does represent, nonetheless, an interesting and general contribution to the understanding of composites. (1971)

    Notes: The effects of fiber volume content, fiber-matrix bonding, heat treatment, and age hardening on the transverse mechanical properties of undirectional aluminum matrix fibrous composites have been investigated. Test results have indicated that the increase of the matrix strength is directly responsible for the increase of the transverse strength of a composite fabricated under heat-treated conditions, as compared with the corresponding strength for the annealed condition. The composite transverse tensile strength and elastic modulus have been calculated by using the finite-element method and the von Mises-Hencky criterion. Both the square and hexagonal arrays have been considered for the fiber configuration in the matrix. The analytical results are compared with the experimental data obtained at room temperature and low strain rate.
