1. 1. Propulsion modelling of a generic submarine propeller

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Gustav Boman; [2023]
   Keywords : OpenFOAM; CFD; actuator line model; rotor disk; actuator disk; INSEAN E1619; propeller;

   Abstract : 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. READ MORE

3. 2. Multiscale mechanical modeling of paperboard

   University essay from Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

   Author : Gustav Boman; [2022]
   Keywords : Paperboard; micromechanics; multiscale; fiber; X-ray; RVE; Technology and Engineering;

   Abstract : 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. READ MORE

4. 3. Asymmetries in shaped charges

   University essay from KTH/Skolan för teknikvetenskap (SCI)

   Author : Gustav Boman; [2021]
   Keywords : ;

   Abstract : 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. READ MORE
