1. 1. Comparison of Achieved Fuel Savings on Ships by Different Wind Propulsion Systems Using a 3-DoF Resistance Model

   Master-uppsats, KTH/Marina system

   Författare :Severi Sarsila; [2022]
   Nyckelord :;

   Sammanfattning : This thesis aims to determine how different wind propulsion systems should be sized in order to achieve comparable fuel savings. The selected wind propulsion systems for the comparison are Dynarig, rigid wing sail and rotor sail. To answer this question, a performance prediction program based on a 3 Degree of Freedom resistance model was developed. LÄS MER

3. 2. Efficient seakeeping performance predictions with CFD

   Master-uppsats, KTH/Marina system

   Författare :Benjamin Lagemann; [2019]
   Nyckelord :added wave resistance; CFD; Courant-adapted time step; Euler ˛flow; FINE Marine; inviscid flow; k-ω SST-Menter; KVLCC2; RANS; regular waves; seakeeping; sub-cycling acceleration; time discretization; viscous flow;

   Sammanfattning : With steadily increasing computational power, computational fluid dynamics (CFD) can be applied to unsteady problems such as seakeeping simulations. Therefore, a good balance between accuracy and computational speed is required. LÄS MER

4. 3. Parametric Hull Form Variation and Assessment of Seakeeping Performance

   Master-uppsats, KTH/Marina system

   Författare :Aina Pons Roser; [2018]
   Nyckelord :;

   Sammanfattning : This Master Thesis is about the assessment of the seakeeping performance of different ships subjected to hull parametric variations. The latest version of the potential flow CFD software Shipflow in combination with a CAD platform (CAESES) have been used to carry out the evaluations. LÄS MER
