1. Optimisation of the Flow Process in Engine Bays - 3D Modelling of Cooling Airflow
Sammanfattning : The focus of today’s automotive industry is to reduce emissionsand fuel consumption of all vehicles. Concentrating on the truckindustry, the last 20 years have focused largely on cutting emissionsof particulate matter and nitrogen oxides. For the future, attentionwill be on fuel consumption and emissions of carbon dioxide. LÄS MER
2. Perspectives of Aerodynamic Drag and Cooling Airflow for Heavy-Duty Trucks - Reconsidering European Total Length Legislation
Sammanfattning : Increasing fuel prices and constantly lowered emission legislation forces the vehicle industry to develop new methods for propelling vehicles and to optimize 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
3. Experimental study of an intermittent ventilation system in high occupancy spaces
Sammanfattning : Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. LÄS MER
4. On Tyre Rotation Modelling and Cooling Flow Measurements
Sammanfattning : With the technological computer advancements, vehicle development is relying more and more on simulations as an alternative to testing. A similar trend follows in aerodynamic development of vehicles where Computational Fluid Dynamics(CFD) simulations are increasing in complexity and accuracy. LÄS MER
5. Investigation of Rear-Mounted Cooling Module Installations for Heavy Vehicles
Sammanfattning : Due to stricter emissions legislations and increasing fuel prices vehicle efficiency must be improved. A trend that has been seen during recent years is increased engine power for many vehicle segments. Different exhaust gas after-treatment systems have also been introduced to be able to meet the emission demands. LÄS MER
