3. Pulp washing - Determining local properties using a new measurement technique
Sammanfattning : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will save a substantial amount of energy, reduce costs by reducing the need for make-up chemicals and improve the bleaching process. There are many discrepancies in the literature, however, as to how different parameters influence washing efficiency. LÄS MER
4. Pulp displacement washing - An investigation of the influence of fibre and bed properties using a novel measurment technique
Sammanfattning : There are many incentives for making the pulp washing process as efficient as possible: an efficient separation of the pulp from the black liquor will increase energy efficiency, reduce costs by minimizing the need for make-up chemicals and improve the bleaching process. Research in this area has, however, been more or less neglected and in the existing literature there are many discrepancies as to how different parameters influence the washing process. LÄS MER
5. Acoustical properties of earplugs
Sammanfattning : In this study an experimental setup for measurements of high impedance objects in ducts, yielding the acoustical Two-Port properties of the object, is applied to earplugs. A frequently used experimental setup for measuring objective acoustical properties of earplugs is that of artificial ears. Great effort is spent on duplicating the human ear. LÄS MER
