1. Propulsion modelling of a generic submarine propeller
Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : Self propulsion modelling is important in order to accurately simulate ships and submarinesusing Computational Fluid Dynamics (CFD). However, fully resolved simulations of hull andpropeller geometries are computationally heavy and time consuming. As such there is a greatinterest in lower order CFD models of propellers. LÄS MER
2. Multiscale mechanical modeling of paperboard
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaperSammanfattning : This thesis considers an investigation into the possibilities of creating a reasonably accurate multiscale material model for paperboard, with geometry based on X-ray scans of small paperboard samples. The modeling takes place in the software Multiscale Designer by Altair Engineering Inc. LÄS MER
3. Asymmetries in shaped charges
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : This thesis concerns the effects of a select few asymmetries on a jet formingshaped charge. A Shaped charge(SC) is a formed explosive with metal liner thatcollapses under the detonation. The resulting shockcompression results in a jetof metal being shot forward in up 10km/s. LÄS MER
4. Utvärdering av metoder for feldetektering av planetväxlar för mutterdragare
Master-uppsats, KTH/Maskinkonstruktion (Inst.)Sammanfattning : Atlas Copco utfor accelererade livslangdsprov pa sina planetvaxlar for mutterdragare genom attkora dem med konstant hastighet och konstant moment tills de havererar. Foretaget onskade ettsatt att under drift detektera tidiga fel i vaxeln for att kunna avbryta testerna medan skadorna fortfarande ar i ett tidigt stadium. LÄS MER
