1. Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts
Sammanfattning : Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. LÄS MER
2. Innovative noise control in ducts
Sammanfattning : The objective of this doctoral thesis is to study three different innovative noise control techniques in ducts namely: acoustic metamaterials, porous absorbers and microperforates. There has been a lot of research done on all these three topics in the context of duct acoustics. LÄS MER
3. Particle-laden Turbulent Wall-bounded Flows in Moderately Complex Geometries
Sammanfattning : Wall-bounded turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the carrier and the particulate phase is elevated to a higher level when introducing geometrical complexities such as curved walls. LÄS MER
4. Lagrangian Particles in Turbulence and Complex Geometries
Sammanfattning : Wall-dominated turbulent dispersed multiphase flows occur in a variety of industrial, biological and environmental applications. The complex nature of the arrier and the dispersed phase is elevated to a higher level introducing geometrical complexities such as curved walls. 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
