1. Analysis of Flow Structures in Wake Flows for Train Aerodynamics
Abstract : Train transportation is a vital part of the transportation system of today anddue to its safe and environmental friendly concept it will be even more impor-tant in the future. The speeds of trains have increased continuously and withhigher speeds the aerodynamic effects become even more important. READ MORE

2. Slipstream and Flow Structures in the Near Wake of High-Speed Trains
Abstract : Train transportation is a vital part of the transportation system of today. Asthe speed of the trains increase, the aerodynamic effects become more impor-tant. One aerodynamic effect that is of vital importance for passengers’ andtrack workers’ safety is slipstream, i.e. READ MORE

3. Investigation on Propeller-Rudder Interaction by Numerical Methods
Abstract : The axial forces in a propeller-rudder interactive system working in uniform flow are theoretically studied: In a steady linear method the propeller is represented by bound and free vortex systems, the rudder by vortex and source filaments and the rudder wake by free vortex filaments. A lifting-line analysis method predicts the propeller characteristics. READ MORE

4. Marine Propulsion System Performance Beyond the Propulsive Factors
Abstract : The marine propulsion system often operates in the wake of the ship it is mounted on. This implies that the propulsion system affects the flow around the hull, and the inflow to the propulsion system is dependent on the hull shape. READ MORE

5. Coordination of Heavy-Duty Vehicle Platooning
Abstract : A network-wide coordination system for heavy-duty vehicle platooning with the purpose of reducing fuel consumption is developed. Road freight is by far the dominating mode for overland transport with over 60 % modal share in the OECD countries and is thus critically important for the economy. READ MORE
