1. Non-Spherical Particle Interaction in Duct and Jet Flow
Sammanfattning : Wood waste is the most popular biomass recourse for many nations. Burned wood can, direct or indirect, release one of the greenhouse gases, carbon dioxide. The process can still be seen as a renewable source of energy since replanting of the trees and crops are consuming nearly the same amount of carbon dioxide through photosynthesis. LÄS MER
2. Experimental study of turbulent flows through pipe bends
Sammanfattning : This thesis deals with turbulent flows in 90 degree curved pipes of circular cross-section. The flow cases investigated experimentally are turbulent flow with and without an additional motion, swirling or pulsating, superposed on the primary flow. LÄS MER
3. Numerical investigation of the flow and instabilities at part-load and speed-no-load in an axial turbine
Sammanfattning : Global renewable energy requirements rapidly increase with the transition to a fossil-free society. As a result, intermittent energy resources, such as wind- and solar power, have become increasingly popular. However, their energy production varies over time, both in the short- and long term.

4. Vibrant bodies of swirling flow : On the limits of mechanical power transformation
Sammanfattning : This thesis pinpoints the intertwined nature of inertia. A vibrant body of a swirling flow is neither just a flow nor a body. It is both. LÄS MER
5. A Study of the Initial Mould Filling during Up-hill Ingot Casting
Sammanfattning : The fluid flow in the mould during up-hill teeming is of great importance for the quality of the cast ingot and thereby the quality of the final steel products. At the early stage of the filling of an up-hill teeming mould, liquid steel flows with a high velocity from the runner into the mould. LÄS MER
