  • Heat Transfer in a New Type of Heat Exchanger for Divided Solids
  • 1979

    • A new type of horizontal, rotating drum heat exchanger is described, which is intended for indirect heat transfer between two streams of solids or for indirect cooling or heating a stream of solids. The heat exchanger is baffled internally and the baffles have three purposes: a transport of the solids, enlargement of the heat transfer area and agitation of the particulate bed in order to achieve good mixing. Rates of heat transfer were measured for streams of four kinds of solids material: two types of sand, glass beads and steel shot. The rate of heat transfer-increased with increasing speed of rotation and fill of the particle bed. The mean particle diameter was the most important of the particle properties. Overall heat transfer coefficients were found to be higher than for most other types of indirect heaters and coolers for solids. A model of the heat transfer process is presented in which the whole resistance to heat transfer is assumed to be in the particle layers in the vicinity of the heat transfer wall. This resistance consists of two parts, one time-independent between the wall and the bed and one time-dependent in the bed itself. The model is shown to be capable of predicting the rates of heat transfer accurately.

  • Electronic spectra of dithieno analogues of phenanthrene
  • 1979
  • Ingår i: Chemical Physics. - : Elsevier BV. - 0301-0104. ; 40:3, s. 397-404
  • Tidskriftsartikel (refereegranskat)abstract
    • The magnetic circular dichroism (MCD) spectra of some dithieno analogues of phenanthrene: benzo [2,1-b;3,4-b′] dithiophene (I) benzo [1,2-b;4,3-b′] dithiophene (II), benzo [1,2-c;3,4-c′] dithiophene (III) and benzo [1,2-b;3,4-b′] dithiophene (IV) are reported. For I–III the spectra corresponding to two different transition moment directions could be obtained from low-temperature linear dichroism spectra. The results compare well with theoretical energies, oscillator strengths, moment directions and MCD B-terms which were obtained from semi-empirical quantum mechanical calculations in the π-electron approximation.

  • A method for determination of the refractive index in a region of absorption. Anomalous dispersion of CS2 in the UV range
  • 1975
  • Ingår i: Chemical Physics. - : Elsevier BV. - 0301-0104. ; 8:1-2, s. 223-230
  • Tidskriftsartikel (refereegranskat)abstract
    • A method is described for determining the refractive index of, e.g., a liquid solution, within an absorption band by studying the linear dichroism generated by different reflections at inclined optical incidence. The method requires a sensitive differential photometric technique, such as that accomplished in a circular dichroism spectrometer.The refractive index of CS2 is reported in the region 260–450 mm. and the result compared to that obtained from a Kramers-Kronig integration on the 320 nm absorption band. Though this band is fairly isolated the experimentally gained result was found more reliable. This was due to difficulties in obtaining an accurate absorption coefficient of liquid CS2 as well as to the fact that the integration had to be restricted to a finite spectral range.
