Abstract: In the mechanical pulping process, wood is treated in compression and in shear at high temperatures in the wet state, to separate the fibers and also to increase the bonding ability and ...

Abstract: Constitutive modeling and related numerical issues in conjunction with the macroscopic analysis and simulation of cold compaction and subsequent solid phase sintering of hard-metal are discussed. ...

Abstract: A numerical and analytical investigation is performed on a dissolved air flotation (DAF) pilot tank by using the residence time distribution (RTD) of the conservative dye rhodamine measured with a fluorometer. The experiments ...

Abstract: The effect of hydraulic transients on water and sewage pipes is studied by measuring the pressure and the strain in pipes simultaneously during field conditions. Both the axial and circumferential strains were recorded for ...

Abstract: This paper describes current practice in road surface and subsurface drainage in Sweden and analyzes the necessity for adaptation of the planning, construction, operation, maintenance and monitoring of road drainage measures ...

Abstract: An image-analysis method developed to study granular flow, the accumulating particle trajectories (APT) method, is shown to be a versatile tool to study the movements of disks. The moving disks, which are provided with ...

Abstract: A model that describes the density-profile evolution in a confined region with a stably stratified fluid, where mixing is induced by a circular, nonswirling turbulent jet discharged vertically down into the fluid is presented ...

Abstract: The effect of particle size distribution in powder compaction has been studied using the discrete element method. Both isostatic compaction and closed die compaction are studied together during ...

Abstract: Simulation of automatic butt-welding of large plates was investigated. Two different steels were considered. The plates were tack-welded before the butt-welding. The simulation includes the ...
