  3. 2. Under-body and Diffuser Flows of Passenger Vehicles

    Författare :Ture Jesper Marklund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bluff bodies; Vehicle aerodynamics; CFD; Wake flow; Boundary layer;

    Sammanfattning : Energy efficient vehicles will be required to meet future emission and fuel consumption requirements. Customers require reduced fuel consumption due to increasing fuel prices and the environmental issues, are drivers to reduce CO2. LÄS MER

  4. 3. Minimize Vortex Drag of a Passenger Car

    Författare :Ture Jesper Marklund; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Boundary layer; Bluff bodies; Vehicle aerodynamics; Wake flow; CFD;

    Sammanfattning : The aerodynamic drag force is the single biggest resistance force for a passenger car toovercome at highway speeds. Since all driving resistance forces can be directly linked tofuel consumption this has become a significant priority in recent years. LÄS MER

  5. 4. Experimental design and vortex analyses in turbulent wake flows

    Författare :Bengt E. G. Fallenius; Jens H. M. Fransson; Henrik Alfredsson; Marianna Braza; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bluff bodies; wake flow; experimental design; vortex detection; flow control; asymptotic suction boundary layer;

    Sammanfattning : A new experimental setup for studies on wake flow instability and its control that successfully has been designed and manufactured, is introduced and de- scribed. The main body is a dual-sided flat plate with an elliptic leading edge and a blunt trailing edge. LÄS MER

  7. 5. An experimental study on the wake behind a rectangular forebody with variable inlet conditions

    Författare :Renzo Trip; Jens Fransson; Olivier Cadot; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bluff bodies; wake flow; asymptotic suction boundary layer; flow control;

    Sammanfattning : The wake behind a rectangular forebody with variable inlet conditions is investigated. The perforated surface of the two-dimensional rectangular forebody, with a smooth leading edge and a blunt trailing edge, allows for boundary layer modification by means of wall suction. LÄS MER
