1. Particle Measurements Using Fluctuations in the Regular Transmittance of Light Through a Particle Dispersion : Concentration and Particles size - Theory, Measurement Principles and Applications for Pulp and Paper Production
Sammanfattning : The regular transmittance of light or similar radiation through a flowing suspension of particles fluctuates because of the random occurrence of particles in the beam.In the work presented here, a theory for this fluctuating behaviour with the emphasison dispersions of mm-length slender cylindrical particles having circular crosssections is given.

3. A study of micro-particles in the dust and melt at different stages of iron and steelmaking
Sammanfattning : The dust particles generated due to mechanical wear of iron ore pellets and clusters formed in molten stainless steel alloyed with rare earth metals (REM) are considered in this study. Firstly, the influence of the characteristics of iron ore pellets, applied load on a pellet bed and partial reduction of the pellets on the size distribution of the generated dust was investigated.

4. Beyond averages – some aspects of how to describe a heterogeneous material, mechanical pulp, on particle level
Sammanfattning : For a more profound understanding of how a process works, it is essential to have a relevant description of the material being processed. With this description, it will be easier to evaluate and control processes to produce more uniform products with the right properties. LÄS MER
5. On the phase-space distribution of heavy particles in turbulence
Sammanfattning : Turbulent fluids laden with small, heavy particles are common in nature. Prominent examples of such turbulent suspensions are water droplets in warm clouds, as well as particulate matter or living organisms in the turbulent upper layer of oceans. LÄS MER
