  2. 1. Investigation of Aerodynamic Resistance of Rotating Wheels on Passenger Cars

    Author : Alexey Vdovin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wheel forces; ventilation resistance; rim design; aerodynamic moment; wheel aerodynamics;

    Abstract : With the current conditions of rising fuel prices and the toughening of environmental legislation for CO2 and other emission gases, vehicle manufacturers around the world are looking into the ways to make their vehicles more energy efficient and therefore more environmentally friendly. One of the ways to achieve this goal is to improve aerodynamic design of vehicles in order to decrease aerodynamic resistance forces. READ MORE

  4. 2. Numerical and Experimental Investigations on Aerodynamic and Thermal Aspects of Rotating Wheels

    Author : Alexey Vdovin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ventilation resistance; wind tunnel; brake cooling; ride height; aerodynamic moment; CFD; rim design; vehicle aerodynamics;

    Abstract : With todays and future environmental legislations for CO2 and other emission gases, all vehicle manufacturers are forced to further develop tools and methods to make their vehicles more energy efficient and environmentally friendly. One option to achieve this is to reduce the aerodynamic resistance since it has a significant influence on the vehicle fuel consumption, especially for velocities higher than 50 km/h. READ MORE

  5. 3. Wheel Housing Aerodynamics of Heavy Trucks

    Author : David Söderblom; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : For trucks in long-haul operation the aerodynamic drag constitutes more than half of the total driving resistance, and by optimising the aerodynamics of thevehicle it is possible to reduce the fuel consumption significantly. The drag of the underbody, including wheels, wheel housings and engine compartment, accounts for a large part of that aerodynamic drag, and very little aerodynamic optimisation has been carried out in this specific area on heavy trucks.

  6. 4. Flow field investigation of rotating wheels on passenger cars

    Author : Christoffer Landström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The importance of aerodynamics of road-going vehicles on the total driving resistance and hence fuel consumption is well known to vehicle manufactures. At present, upper body aerodynamics of passenger cars is relatively well understood. READ MORE

  7. 5. Under-body and Diffuser Flows of Passenger Vehicles

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

    Abstract : 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. READ MORE
