  1. 1. Passenger Car Wheel Aerodynamics

    Author : Christoffer Landström; Chalmers University of Technology; []
    Keywords : 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

  2. 2. Unsteady Numerical Simulations of Flow around Heavy Vehicles, Trains and Passenger Cars

    Author : Jan Östh; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Large Eddy Simulation; fluid dynamics; bluff body flows; flow structures; vehicle aerodynamics; flow control; flow physics; truck aerodynamics; train aerodynamics; car aerodynamics;

    Abstract : In this thesis several simulations have been carried out aimed at improving the knowledgeof vehicle aerodynamics and improving the flow around vehicles with respect to theaerodynamic drag. Four flows around different simplified vehicles have been considered. READ MORE

  3. 3. Aerodynamics of vehicle platooning

    Author : Johannes Törnell; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; close proximity; drag; platooning; cab over engine; aerodynamics; yaw; wake; side wind; truck; inter-vehicle distance; lateral offset;

    Abstract : Many factors are pushing automotive manufacturers to increase the efficiency of their fleets; some of these are legislative (requiring reduced greenhouse gas emissions) as well as ensuring sufficient range and power consumption in electric vehicles. An important part of improving the energy efficiency of road vehicles is reducing their aerodynamic drag. READ MORE
