    Sammanfattning : In Old West Norse there is mention of an Arctic skin and osier boat, which was paddled with Old West Norse (húð)keipr, diminutive keipull, formed on Germanic *kaip- ’bend, unfold’ according to the construction method. In East Norse there was a corresponding wooden boat, e.g. LÄS MER

    Sammanfattning : This thesis focuses on two important topics in the field of fluid mechanics and heat transfer that were treated separately. On the one hand, the flow over rough surfaces, which is not yet completely understood, despite of the fact that it has an important implication in many engineering applications, especially in the naval industry for ships and boats because the friction drag caused by fouling, antifouling coatings and roughness in general impacts the fuel consumption and toxic emissions to the atmosphere.
