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

    Author : Alexey Vdovin; [2013]
    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

  2. 2. Passenger Car Wheel Aerodynamics

    Author : Christoffer Landström; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; tyres; wind tunnel; Passenger car aerodynamics; ground simulation; wheel rotation; drag; wheels;

    Abstract : Current and future requirements for efficiency force the automotive industry to consider all aspects of reducing the energy consumption of road going vehicles. An important aspect of reducing fuel consumption is reduced aerodynamic drag, which at highway cruising speeds is dominating the total drag force for both cars and heavy goods vehicles. READ MORE

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

    Author : Alexey Vdovin; [2015]
    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

  4. 4. Wheel Housing Aerodynamics of Heavy Trucks

    Author : David Söderblom; [2012]
    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.

  5. 5. Investigation of Wheel Housing Flow on Heavy Trucks

    Author : David Söderblom; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Increasing fuel prices and demands for reductions of emissions have led to a considerably increased interest in developing more efficient vehicles. Besides designing more efficient power units with lower fuel consumption and emission levels it is possible to increase the total efficiency of the vehicle by aerodynamic optimization. READ MORE
