1. Endotracheal Suction a Reopened Problem
Sammanfattning : During mechanical ventilation, patients are connected to the ventilator by an endotracheal tube. The tube needs to be cleaned from mucus by suction, which can cause negative effects such as lung collapse, hypoxemia and desaturation. LÄS MER
2. On Suction Box Dewatering Mechanisms
Sammanfattning : In previous studies on suction box dewatering, three mechanisms were identified that determine the dry content of a web, viz. web compression, displacement of water by air and rewetting. LÄS MER
3. Numerical studies of transtion in wall-bounded flows
Sammanfattning : Disturbances introduced in wall-bounded flows can grow and lead to transition from laminar to turbulent flow. In order to reduce losses or enhance mixing in energy systems, a fundamental understanding of the flow stability and transition mechanism is important. LÄS MER
4. Modelling of the pressure distributions in twin-wire blade formers
Sammanfattning : During papermaking, the internal structure of the fibrenetwork constituting the paper is to a dominating extentdetermined in the forming zone of the paper machine. Thisthesis is aimed at studying the pressure distribution in bladeforming sections, which is commonly considered to be a keyquantity of the process. LÄS MER
5. Mechanical modelling of blade forming and drainage of flocculated suspensions
Sammanfattning : A method has been developed for flexible modelling of multi-component twin-wire blade formers. Features such as suction devices, loadable blades, curved blades, and partial contact between the blades and the forming fabrics are easily incorporated. LÄS MER
