Abstract

The project "Multiphase flows in process industry (ProMoni)" 1.1.2001-30.4.2004 was a research consortium carried out jointly by seven research groups from VTT Technical Research Centre of Finland, University of Jyväskylä, Tampere University of Technology, Åbo Akademi University and University of Kuopio. It included modeling, development and validation of numerical methods as well as development of new experimental techniques for multiphase flows found in process industry. The primary fields of application are in fluidized beds and in various processes found in the paper and pulp industry. The total extent of the project was approximately 25 person years and it was funded by the National Technology Agency of Finland, Foster Wheeler Energia Oy, Metso Oyj and Fortum Oyj. The main results reported in this final report of the ProMoni project include: Results from experimental and numerical research of bubbling fluidized beds indicating that modelling produces the bed behaviour realistically and the simulations can be used in developing approximative macroscopic two-phase models. A new gas-solid drag correlation model was successfully used within Fluent CFD code to simulate the typical flow structures in a circulating fluidized bed riser. Several new or newly adapted experimental methods and measuring devices for fibre suspension flows were developed and brought in regular use in laboratory or pilot scale environments. Particle Image Velocimetry and Digital Imaging measurement were developed and used in two-phase flows to measure hydrodynamical interaction and morphology of the dispersed phase. Optical and electrical impedance tomographic devices and related image reconstruction algorithms were developed for non-intrusive measurement of consistency profiles and flow velocity in flows of diffusive fluids such as wood fibre suspensions. More detailed information can be found in numerous publications and reports issued by the participating groups, and referred to in this report.
