21. On Tyre Rotation Modelling and Cooling Flow Measurements
Abstract : 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. READ MORE

23. Aerodynamic Investigation of Truck-Trailer Combinations
Abstract : 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. READ MORE

24. Aerothermal Experimental Investigation of LPT-OGVs
Abstract : This thesis presents the design, commissioning, and experimental data of a newly built turbine facility at Chalmers University of Technology for investigating the ow in the engine exit structure (EES). The EES is the structure located downstream of the lowpressure turbine (LPT) in a jet engine. READ MORE

25. Numerical Investigation of the Aerodynamic Vibration Excitation of High-Pressure Turbine Rotors
Abstract : The design parameters axial gap and stator count of highpressure turbine stages are evaluated numerically towards theirinfluence on the unsteady aerodynamic excitation of rotorblades. Of particular interest is if and how unsteadyaerodynamic considerations in the design could reduce the riskofhigh cycle fatigue (HCF) failures of the turbine rotor. READ MORE
