1. Numerical Investigation of Unsteady Crosswind Aerodynamics for Ground Vehicles
Sammanfattning : Ground vehicles are subjected to crosswind from various origins such as weather, topography of the ambient environment (land, forest, tunnels, high bushes...) or surrounding traffic. LÄS MER
2. 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
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. Vehicle wakes in side wind
Sammanfattning : There is a global push to reduce the energy consumption of passenger vehicles with increasingly stringent targets and regulations. More than one-tenth of Europe's greenhouse gasses are due to passenger vehicles. The aerodynamic drag is a major contributor to energy consumption responsible for more than a quarter of the vehicle's energy usage. LÄS MER
5. Tyre aerodynamics of passenger vehicles
Sammanfattning : 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. LÄS MER
