  1. 16. Validation of CFD simulation with PIV measurements for Open Rotor Noise Predictions

    University essay from KTH/Mekanik

    Author : THOMAS JEAN BERNARD POMMIER; [2015]
    Keywords : ;

    Abstract : CROR means Contra--‐Rotating Open Rotor. Its efficiency is better than usual in aeronautics thanks to its geometry (open rotor and thus high bypass ratio) but also by adding a second rotor. Indeed it enables to recover the swirl loss of the first rotor. However, this engine is rarely used today in civil aviation for acoustic reasons. READ MORE

  3. 17. CFD Investigation of Fluidic Momentum Injection as Alternative to Mechanical High Lift Devices for Boundary Layer Control

    University essay from KTH/Aerodynamik

    Author : Kyle Smith; [2014]
    Keywords : ;

    Abstract : Syftet med detta projekt i aerodynamik ar att prova en metod för kontroll av gränsskiktets beteende med luftinsprutning. En modern vingprofil vid transsonisk hastighet används, som liknar de som finns på de festa kommersiella flygplan. READ MORE

  4. 18. Predicting the Effects of Interaction between Yachts Sailing Upwind

    Abstract : 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.

    Abstract : 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. READ MORE
