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. Tyre aerodynamics of passenger vehicles

   Author : Erik Josefsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; drag; wind tunnel; tyres; aerodynamics; wheels;

   Abstract : To decelerate climate change and limit global warming, there is a need for reducing the environmental impact of vehicles, which can be achieved by increasing their energy efficiency. For a passenger vehicle, one of the largest resistive forces is aerodynamic drag. 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. 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

7. 5. Wheel Modelling and Cooling Flow Effects on Car Aerodynamics

   Author : Teddy Hobeika; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : In recent years, the automotive industry has focused on computer simulations as an alternative to physical testing. This allows for early vehicle optimization, short turn around times, and significant cost savings. READ MORE
