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. Development of a 2D Optimal Path Simulation for Ship-to-Shore Cranes : Safe Trajectories within Interchangeable Obstalce Environments

   University essay from Linköpings universitet/Fordonssystem

   Author : Rickard Green; [2020]
   Keywords : Optimal Path; Control; Control theory; Obstacle; Safe trajectories; LiU; ISY; Reglerteknik;

   Abstract : The most advanced ports as of writing of this report are at least somewhat autonomous. Whether discussing the transporters between crane and stack (temporary storage) or cranes, the ports are shifting into a completely autonomous system. This ultimate goal presents a challenge in regards to unloading and loading cargo ships in the harbour. READ MORE

4. 3. Analysis of the intake grill for marine jet propulsion

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Marcus Söderberg Jansson; [2019]
   Keywords : Intake grill; Waterjet; Fluid Dynamics; Intagsgaller; Vattenjet; Strömning;

   Abstract : Marine waterjet propulsion is a technology that has been developed and refined since the early 1950’ and is proven highly useful for high speed applications with vessels in varying sizes. The intake grill is a component that is mounted in line with the hull to prevent debris from traveling through the waterjet. READ MORE

5. 4. Development of an hydrodynamic hull model for slender planning hulls based on the 2D+t theory

   University essay from KTH/Marina system

   Author : Antoine Caillaud; [2016]
   Keywords : ;

   Abstract : A two-dimensional Boundary Element Method (BEM) based on potential flow theory is developed. Exact body boundary conditions and fully nonlinear free surface boundary conditions are considered in order to accurately model nonlinear wave-body interactions. The two-dimensional symmetric water entry of a wedge is studied. READ MORE

6. 5. Spatial analysis for the distribution of cells in tissue sections

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ruibin Xu; [2014]
   Keywords : clustering methods; physical geography and ecosystem analysis; spatial analysis; proximity methods; 2D hull; geomatics; Earth and Environmental Sciences;

   Abstract : Spatial analysis, playing an essential role in data mining, is applied in a considerable number of fields. It is because of its broad applicability that dealing with the interdisciplinary issues is becoming more prevalent. It aims at exploring the underlying patterns of the data. READ MORE
