  2. 1. Passenger Car Wheel Aerodynamics

    Author : Christoffer Landström; Chalmers tekniska högskola; []
    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

  4. 2. Minimize Vortex Drag of a Passenger Car

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

    Abstract : 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. READ MORE

  5. 3. The Aerodynamic Correlation of a Scale Model with a Full Size Car

    Author : Lasse Malmkjaer Christoffersen; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cooling flow.; Correlation; Experiment; Reynolds number; Road Vehicle Aerodynamics; CFD; Scale model;

    Abstract : Reducing the Worlds consumption of energy has become an important part of the current political and environmental debate. The reasons are obvious: World population is increasing, continued growth in living standards, finite availability of resources and finally green house gas emissions from energy production have to be brought down to stabilize temperatures.
