1. Vortex generator modeling and its application to optimal control of airflow in inlet
Sammanfattning : This dissertation deals with the development of the vortex generator model and its use for the optimization study of vortex generator flow control in high-offset-ed inlets. In the first part, the overview of use of vortex generators and their mechanism is outlined. LÄS MER
2. Computational studies of passive vortex generators for flow control
Sammanfattning : Many flow cases in fluid dynamics face undesirable flow separation due torising static pressure on wall boundaries. This occurs e.g. due to geometry as ina highly curved turbine inlet duct or e. LÄS MER
3. Computational fluid-dynamics investigations of vortex generators for flow-separation control
Sammanfattning : Many flow cases in fluid dynamics face undesirable flow separation due to ad-verse pressure gradients on wall boundaries. This occurs, for example, due togeometrical reasons as in a highly curved turbine-inlet duct or on flow-controlsurfaces such as wing trailing-edge flaps within a certain angle-of-attack range.

4. Experimental and Numerical Investigations of Heat Transfer related to Gas Turbine Applications
Sammanfattning : Gas turbines are broadly used in aerospace and marine propulsion and power production etc.Investigation of heat transfer in gas turbines is a long-lasting and still an active subject ofresearch due to its tremendous importance. LÄS MER
5. Experimental and computational studies of turbulent separating internal flows
Sammanfattning : The separating turbulent flow in a plane asymmetric diffuser with 8.5 degrees opening angle is investigated experimentally and computationally. The considered flow case is suitable for fundamental studies of separation, separation control and turbulence modelling. LÄS MER
