    1. A Review of Recent Electrical Resistance Tomography (ERT) Applications for Wet Particulate Processing (pages 207–215)

      Steven J. Stanley and Gary T. Bolton

      Version of Record online: 4 JUN 2008 | DOI: 10.1002/ppsc.200701126

      ERT provides the capability for in-situ measurement of the time-dependent three-dimensional solid load which often enhances fundamental process understanding. This paper reviews previous work undertaken for applications associated to wet particulate processing. Typical results from a number of examples from both, research and industrial environments are presented.

    2. Intercomparison of Inversion Algorithms for Particle-Sizing Using Mie Scattering (pages 216–230)

      Norbert Riefler and Thomas Wriedt

      Version of Record online: 3 SEP 2008 | DOI: 10.1002/ppsc.200700039

      The applicability of different inversion algorithms to retrieve a particle size distribution from light scattering is examined. The investigation is based on simulations and application of different kinds of noise. The convergence properties of the scattering inversion are investigated with respect to the number of size classes which can be retrieved from these simulated measurements.

    3. Measurements on Particle Size Distribution and Concentration by Transmission Fluctuation Spectrometry with Temporal Correlation (pages 231–243)

      Bin Yu, Jianqi Shen, Yamin Xu, Ulrich Riebel and Xiaoai Guo

      Version of Record online: 4 JUN 2008 | DOI: 10.1002/ppsc.200701128

      TFS-TC is a new method for particle analysis which may be used for real-time, inline/online applications due to its simplicity. In this work, an experimental study of the TFS-TC measurement is presented up to high particle concentrations. By introducing an empirical correction a broad range of particle size and concentration can be retrieved.

    4. Locally Resolving Measurements of PSD, Particle Concentration and Particle Velocity by Means of TFS with Dual Beams (pages 244–258)

      Xiaoai Guo and Ulrich Riebel

      Version of Record online: 26 MAY 2008 | DOI: 10.1002/ppsc.200701138

      Transmission fluctuation spectrometry with spatial correlation (TFS-SC) is based on transmitting two beams through a flowing suspension determining the spatial correlation of the transmission fluctuations. This method appears to be promising for application in the local resolving of measurements of PSD, particle concentration and particle velocity in two-phase flows, both in the laboratory and in process control.

    5. Flow Pattern Tracing for Mass Flow Rate Measurement in Pneumatic Conveying Using Twin Plane Electrical Capacitance Tomography (pages 259–265)

      Volodymyr Mosorov

      Version of Record online: 3 SEP 2008 | DOI: 10.1002/ppsc.200700034

      This paper presents an original concept for automatic determination of the time intervals for calculation of the mass flow rate of an intermittent flow using a twin-plane ECT system. The concept allows a solids mass flow rate to be calculated more accurately. Preliminary results of such mass flow rate measurements of a gas-solid flow during pneumatic conveying are presented.

    6. Mechanical Characterization of Protein Crystals (pages 266–276)

      Stephan Tait, Edward T. White and James D. Litster

      Version of Record online: 10 JUL 2008 | DOI: 10.1002/ppsc.200701112

      The mechanical properties of four crystalline materials (two proteins and two non-proteins) were measured with an indentation technique. It was found that mechanical properties show significant differences. Experimental findings were interpreted in terms of relative susceptibility to breakage, attrition and secondary nucleation in stirred industrial crystallizers.
