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. Aerothermal Experimental Investigation of LPT-OGVs
Sammanfattning : 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. LÄS MER
3. Design of an Experimental Facility for Investi- gating the Flow in a Low Pressure Turbine Exit Structure
Sammanfattning : This report presents the design of a turbine facility for investigating the flow in the EES located at Chalmers University of Technology. The EES is the structure located downstream of the LPT in a jet engine. In this rig, in order to generate realistic inlet boundary conditions for the EES, an LPT stage is located upstream of the EES.

4. Experimental Investigation of the Aerodynamics and Heat Transfer in an Intermediate Turbine Duct
Sammanfattning : In today’s aero engines with large bypass ratios, the difference in diameter between the high pressure turbine and the downstream turbine, being either an intermediate or low pressure turbine, is large. There is also scope to further increase it, in order to increase the efficiency of the downstream turbine and enabling use of larger diameter fans. LÄS MER
5. Aerothermal Study of Intermediate Turbine Ducts
Sammanfattning : An intermediate turbine duct guides the flow from the smaller diameter high pressure turbine to the downstream larger diameter intermediate or low pressure turbine. It is typically equipped with a structural vane transferring loads for the core to the external parts, and supplies the core with necessary services such as oil and air. LÄS MER
