Multiphase flows in process industry- project (ProMoni) was a by Tekes and Finnish industry funded three year research project. Five Finnish universities and research units were working in the project in different applications of multiphase flows. All the results are reported in the projects final report1. The aim of this report is to give detailed insight to the work which was made by TUT:s Experimental fluid dynamics group. In the project were developed methods for dispersed phase characterization, for turbulence measurements in multiphase flows and for turbulence characterization. Digital Imaging and Particle Image Velocimetry were the used measurement methods. In institute of Energy and Process Engineering at TUT has been developed Experimental Fluid Mechanics knowledge based on optical and digital imaging measurement methods. The work has been continued several years with support of TEKES and various industrial partners. At this ProMoni-project has been reached a level, which enables research of new key tasks in multiphase fluid mechanics. The project has enabled the research of interaction of dispersed phase and turbulence and this leads to many new inventions industrial applications. This is the main motivation to publish this separate report.
