1. Mechanical modelling of blade forming and drainage of flocculated suspensions
Abstract : 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. READ MORE

2. Alternatives for Finite Element Analysis of Blade Forging
Abstract : This thesis is a theoretical and numerical study of the weaknesses and capabilities of alternative finite element procedures for simulation of the blade forging problem and also an analysis of the practical aspects of that process. An overview is presented of the finite element method for non-linear problems with elastoplastic constitutive relations, focusing on quasistatic implicit and dynamic explicit approaches. READ MORE

3. Modelling of the pressure distributions in twin-wire blade formers
Abstract : 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. READ MORE

4. On the Modelling of Mechanical Dewatering in Papermaking
Abstract : Most of the water fed into a paper machine is removedmechanically in the forming and press sections. One of thefactor which has an important influence on mechanicaldewatering, i.e. in both forming and pressing, is thestress-strain behaviour of the fibre network. READ MORE

5. Investigations of Heat Transfer and Fluid Flow in the Pocket Region of a Gas Turbine Engine and Cooling of a Turbine Blade
Abstract : In the present work, heat transfer within gas turbine applications are investigated bothexperimentally and numerically. The main content concerns heat transfer and fluidflow over the pocket region and cooling of a turbine blade. READ MORE
