1. Aerodynamics of vehicle platooning
Sammanfattning : 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. LÄS MER
2. Aerodynamics of two trucks driving in close-proximity
Sammanfattning : There are several factors driving the development of vehicles with higher efficiency in society, chief among them are the emissions of greenhouse gases and their contribution to global warming. Therefore, there is a strong incentive to improve heavy-duty trucks' energy efficiency, supported by new legislation. LÄS MER
3. Unsteady Numerical Simulations of Flow around Heavy Vehicles, Trains and Passenger Cars
Sammanfattning : 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. LÄS MER
4. Aerodynamic Investigation of Truck-Trailer Combinations
Sammanfattning : In today’s society, increasing fuel prices and the constantly evolving emission legislation, forces the vehicle industry to develop new techniques for the propul- sion of vehicles, and optimization of existing technology. Trucks constitute a significant proportion of the transportation system, consequently it is of great importance to ensure as low an impact as possible on the environment. LÄS MER
5. Optimization of the Flow Process in Engine Bays - 3D Fan Modeling Strategies
Sammanfattning : In todays automotive industry there is an apparent need and demand for low fuel consuming vehicles. This is a fact every automotive OEM is aware of and the heavy duty truck industry is no exception. With a cooling fan in today’s trucks that typically consumes of the order of magnitude 50bHp fully engaged - reducing this loss is very important. LÄS MER
