1. Propulsion modelling of a generic submarine propeller
University essay from KTH/Skolan för teknikvetenskap (SCI)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

2. A simplified vortex method for wind turbine simulation
University essay from KTH/Strömningsmekanik och Teknisk AkustikAbstract : A new vortex model for wind turbines was developed in order to evaluate the loads at the blades and other important characteristics of interest for the wind industry such as power and thrust coefficients. Nowadays, the calculation of these quantaties is done in a reliable and precise manner with LES simulation using actuator line or actuator disk models. READ MORE

3. Partially Parabolic Wind Turbine Flow Modelling
University essay from KTH/MekanikAbstract : Climate change is an evermore urging existential treat to the human enterprise. Mean temperature and greenhouse gas emissions have in-creased exponentially since the industrial revolution. But solutions are also mushrooming with exponential pace. READ MORE

4. Accuracy of transient versus steady state forces on a rudder operating in a propeller slipstream
University essay from Umeå universitet/Institutionen för fysikAbstract : In computational fluid dynamics (CFD), a transient simulation is in general more costly than computing the steady state of the system, if such a state exists. The velocity field produced by the propeller blades upstream of a rudder is transient in nature, and rudder design using CFD may therefore become very time-consuming. READ MORE

5. Propulsion Unit of a 3DOF Helicopter
University essay from Linköpings universitet/Fluida och mekatroniska system; Linköpings universitet/Tekniska fakultetenAbstract : This Bachelor thesis is a part of a bachelor project which includes building, programming and controlling a 3DOF tandem helicopter. This particular report deals with the propulsion units, i.e. the motors and propellers of the helicopter. READ MORE
