2. Computational studies of passive vortex generators for flow control
Abstract : 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. READ MORE

3. A Large-Scale Facility for Investigation of Intermediate Turbine Ducts: Design, Implementation and Initial Tests
Abstract : Intermediate turbine ducts are used in modern multi-spool jet engines for guiding the flow from the high-pressure turbine to the low-pressure turbine. The demand for lighter, more efficient and more environmentally friendly aircraft engines requires the new jet engines to have higher by-pass ratios. READ MORE

4. Analytical and Numerical Investigations of Steady and Unsteady Turbulent Swirling Flow in Diffusers
Abstract : Swirling flows are found in many technical applications, e.g. turbines, pumps, fans, compressors and combustors. The objective of the present work is to acquire an understanding of the physics of swirling flow in general and unsteady swirling flow in draft tubes of water turbines in particular. READ MORE
