2. 1. Analysis of the Unsteady Flow Field of a Passenger Vehicle

   Author : Lennert Sterken; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wind tunnel; Wake; CFD; Pressure measurements; Extensions; Yaw response; External aerodynamics; Aerodynamic forces;

   Abstract : Political legislation and consumer requirements for a sustainable society require that vehicle manufacturers focus on reduced fuel consumption and lower emissions. Areduction in the overall energy consumption can be directly linked to a decrease of the driving resistance, where the aerodynamic drag significantly contributes at velocities above 70km/h.

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

6. 4. 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

7. 5. Energy efficiency and ventilation in Swedish industries barriers, simulation and control strategy

   Author : Patrik Rohdin; Bahram Moshfegh; Hazim Awbi; Magnus Karlsson; Alfred Moser; Linköpings universitet; []
   Keywords : Industrial energy efficiency; Industrial ventilation; Barriers; Driving forces. CFD; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The energy issue is presently in focus worldwide. This is not only due to increasing environmental concern regarding energy related emissions, but also due to the trend of increasing energy prices. Energy usage in the industrial sector in Sweden today represents about one third of the national energy use. READ MORE
