6. Experimental Investigation of the Aerodynamics of a Sailing Cargo Vessel with Four Rigid Wingsails under Unsteady Sailing Conditions
Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanikSammanfattning : Wind propulsion is a traditional way to propel ships over the oceans. In the recent development towards more sustainable shipping, sailing is considered in the industry again with high momentum. For a modern merchant ship, the aerodynamic forces generated on the particular rigging are unusual. LÄS MER
7. Utveckling av kraftsensors-rigg för vindtunnel : En ny design för kraftsensors-rigg för Mittuniversitets vindtunnel
Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskapSammanfattning : En vindtunnel används för att simulera luftflödet som verkar på till exempel en nerskalad modell av en verklig flygplansvinge eller ett fordon. Detta hjälper att förstå och ta fram de komponenter som påverkar interaktionen samt krafter och moment. LÄS MER
8. Development of a Low Speed Wind Tunnel Test Campaign
Master-uppsats, KTH/FlygdynamikSammanfattning : This study was performed to investigate aerodynamic characteristics of the 37.5% scaled down Green Raven MK18 airframe, to evaluate boundary corrections method, and to investigate on support interference. LÄS MER
9. Load Control Aerodynamics in Offshore Wind Turbines
Master-uppsats, KTH/Kraft- och värmeteknologiSammanfattning : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. LÄS MER
10. Undertray Design and Development Procedure with CFD : An Optimization Study of Different UndertrayDesigns with CFD Computations
Master-uppsats, KTH/Strömningsmekanik och Teknisk AkustikSammanfattning : Race car aerodynamics has played a vital part to improve lap times over the years of motor racing. Having good road adhesion with slick tires and aerodynamic downforce will increase the vehicles maximum lateral force and thus higher cornering speeds can be achieved. LÄS MER
