    Tube array heat transfer in fluidized beds a study of particle size effects (1989)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 35 (1989), S. 1170-1176 
    Details
    ISSN: 0001-1541
    Keywords: Chemistry ; Chemical Engineering

    Notes: Experiments were performed with an array of horizontal tubes, arranged in a regular equilateral triangular pattern, immersed in a fluidized bed operating at 812 K. Data are reported for heat transfer between the bed and a centrally-located tube in the array. Both total and radiative heat transfer rates were measured for superficial velocities spanning the range from packed bed conditions to over twice the minimum fluidization velocity. Results are presented for five differentsize particles. Local heat transfer values, measured around the tube periphery, and integrated averages are reported for all test conditions.Comparisons are also made between the heat transfer behavior of a tube in an array and that for a single tube in a hot fluidized bed under the same overall operating conditions. The results of this comparison suggest that the two mechanisms, gas convection and radiation, are competing effects.

    Cure analysis of sheet molding compound in molds with substructures (1989)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 29 (1989), S. 740-748 
    Details
    ISSN: 0032-3888
    Keywords: Chemistry ; Chemical Engineering
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology , Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics , Physics
    Notes: The effects of material flow, heat transfer, part geometry, and curing agents on the cure of sheet molding compounds (SMC) in molds with substructures were analyzed both experimentally and numerically. It was found that heat transfer during mold filling has a profound effect on the cure pattern, especially for fastcure resins molded for parts with thin dimensions.

    Analysis of transient sorption and permeation in heterogeneous media (1986)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 26 (1986), S. 1045-1049

    Notes: Experimental data on hexane vapor sorption in phase-segregated polybutadiene/polystyrene blends are reported, which exhibit seemingly non-Fickian characteristics that previous workers with styrene/butadiene copolymer attributed to a diffuse interphase. These data, plus results derived from a model of sorption in heterogeneous media containing a slowly permeable dispersed phase, indicate that the mere presence of two phases with different diffusion time constants is a sufficient condition for apparently non-Fickian overall behavior. Consequently, definitive morphological inferences cannot be drawn from such observations. In addition, results of modeling the corresponding permeation process are analogous to those obtained in an earlier study of permeation with immobilizing chemical reaction.
