11. On Subscale Flight Testing : Applications in Aircraft Conceptual Design
Sammanfattning : Downscaled physical models, also referred to as subscale models, have played an essential role in the investigation of the complex physics of flight until the recent disruption of numerical simulation. Despite the fact that improvements in computational methods are slowly pushing experimental techniques towards a secondary role as verification or calibration tools, real-world testing of physical prototypes still provides an unmatched confidence.

12. Truck tyre rolling resistance : Experimental testing and constitutive modelling of tyres
Sammanfattning : Global warming sets a high demand to reduce the CO2 emissions of vehicles. In the European Union heavy-duty road transports account for 6 % of the total greenhouse gases and one of the main factors affecting these emissions is related to the rolling resistance of tyres. LÄS MER
13. Modelling and experimental testing of truck tyre rolling resistance
Sammanfattning : Truck transport offers a versatile way to ship goods in regional, long haulage and urban applications. However, the heavy truck sector accounts for 6 % of total greenhouse gas emissions in the European Union. Therefore, there is a need for a substantial reduction of these emissions to secure the sustainability of Earth for future generations. LÄS MER
14. Aerodynamic Aspects of Propulsion Integration for Next-generation Commercial Aircraft
Sammanfattning : Propulsion integration is one of the most challenging aspects of aircraft design. It requires a multidisciplinary approach involving aerodynamics, propulsion, structures, weight, noise, and control systems. LÄS MER
15. Wheel Modelling and Cooling Flow Effects on Car Aerodynamics
Sammanfattning : 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. LÄS MER
