  1. 21. Predicting the Effects of Interaction between Yachts Sailing Upwind

    Master-uppsats, KTH/Marina system

    Författare :Olof Detlefsen; [2012]
    Nyckelord :;

    Sammanfattning : The ever-growing yachting industry has come to play an important role in the maritime sector, resulting in an increasing demand for highly technologically advanced cruising and racing sailing yachts. In the aim of producing faster yachts and faster sails designers and sailors has come a long way understanding the science of sailing. LÄS MER

  3. 22. Motorcycle Cornering Improvement : An Aerodynamical Approach based on Flow Interference

    Master-uppsats, KTH/Aerodynamik; KTH/Mekanik

    Författare :Vojtech Sedlak; [2012]
    Nyckelord :aerodynamic; fluid mechanics; interference; blockage; airfoil; wing; bluff body; motorcycle; moto; motorbike; MotoGP; road racing; aerodynamik; fluid mekanik; flöde interferenser; vinge; motorcyckel; MotoGP; roadracing;

    Sammanfattning : A new aerodynamic device, based on flow interference effects, is studied in order to significantly improve the cornering performance of racing motorcycles in MotoGP. After a brief overview on why standard downforce devices cannot be used on motorcycles, the new idea is introduced and a simplified mechanic analysis is provided to prove its effectiveness. LÄS MER

  4. 23. Utveckling av provmetodik för HVAC på lastbil : - Klimatprovning i vindtunneln CD7

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Björn-Emil Jonsson; Medförfattare Jimmy Tedenäs; [2011]
    Nyckelord :;

    Sammanfattning : I detta examensarbetet undersöks hur provningen av HVAC på lastbilar skall utföras i klimatvindtunneln CD7 som Scania färdigställer till år 2013. HVAC omfattar kupéuppvärmning, ventilation samt AC och har därmed en stor betydelse för klimatkomforten inne i lastbilshytten. LÄS MER

  5. 24. Utveckling av provmetodik för HVAC på lastbil : Klimatprovning i klimatvindtunneln CD7

    Uppsats för yrkesexamina på avancerad nivå, Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Jimmy Tedenäs; Björn-Emil Jonsson; [2011]
    Nyckelord :CWT; test methodology; HVAC; climatic testing; Klimatvindtunnel; HVAC; provmetodik; klimatprovning;

    Sammanfattning : The issue about how Scania shall perform HVAC tests in the climatic wind tunnel CD7, which Scania is about to complete by year 2013, has resulted in four test methods for truck HVAC and also a test method structure. The test methods have been chosen to focus on sun, snow and rain simulations. LÄS MER

  7. 25.  3D CFD-analysis of conceptual bow wings

    Master-uppsats, KTH/Marina system

    Författare :Paul Nielsen; [2011]
    Nyckelord :;

    Sammanfattning : As a small step towards their long-term vision of one day producing emission free vessels, Wallenius em-ployed, in 2009, Mårten Silvanius to carry out his master thesis for them in which he studied five different concepts to reduce the overall fuel consumption using wind powered systems. The vessel on which his study was performed is the 230 m LCTC vessel M/V Fedora. LÄS MER
