1. Fluid flow through and deformation of wood fiber networks
Sammanfattning : Cellulose-based commercial items such as paper and laminated flooring are vital to the local economy of northern Sweden. These products are commonly manufactured in suspension where fluids such as water or air are drained through the fiber network in some value-added steps in the manufacturing process. LÄS MER
2. Numerical Simulations of Turbulent Flows at Widely Different Mach Numbers
Sammanfattning : The present thesis mainly focuses on the numerical simulation of the turbulent flow field and acoustics developed in different industrial applications. The study covers a large range of Mach numbers, starting from incompressible regimes and ending with a fully compressible flow. LÄS MER
3. Super-grid Linear Eddy Model (SG-LEM): Efficient mode- and regime-independent combustion closure for Large Eddy Simulation (LES)
Sammanfattning : Next-generation combustion technology such as ‘lean burn’ and HCCI (Homogeneous Charge Compression Ignition) present new challenges for combustion modelling. The presence of locally varying combustion modes (premixed vs. non-premixed) and regimes (fast/non-fast chemistry vs. LÄS MER
4. Modelling the aerodynamics of iron ore pelletizing kilns
Sammanfattning : In an iron ore pelletizing plant, crude ore is upgraded to pellets to be used as feedstock in steel-making plants. As part of a grate-kiln pelletizing plant, the rotary kiln is an indurating furnace in which the pellets are sintered. LÄS MER
5. Experiments and numerical modelling of the SMC and autoclave processes
Sammanfattning : The work presented in this thesis focus on the flow taking place in two industrialmanufacturing methods for composite manufacturing. The first method underinvestigation is compression moulding of Sheet Moulding Compound (SMC). LÄS MER
