The high pressure turbine, producing 70% of engine power in one or two stages, is the core component of an aircraft engine. High dependence of engine efficiency and life on this component makes the performance of this module extremely important. The flow in turbines is three dimensional, complex and unsteady due to the wakes, shock system and secondary flows. Moreover, high pressure turbines run under high thermal loads most of the time beyond the material limits. Hence, hot section components need to be cooled down effectively in a compact design. Beside all of those complexities, the understanding of the turbine flow field requires a lot of effort. This presentation will focus on the recent experimental investigations of turbine flow field. Newly developed experimental methods to measure quantities with high accuracy are also addressed. Finally, relevant research activities at TUSAS Engine Industries, Inc. are presented.
Tolga Yasa received her Bachelor degree in Mechanical Engineering in 2002 from Istanbul Technical University (Istanbul, Turkey), Master of Applied Science degree in 2005 from Istanbul Technical University (Istanbul, Turkey), in parallel he completed research master program at von varman Institute. He obtained his PhD degree in Mechanical Engineering in 2008 from Catholic University of Leuven (Louvain-la-Neuve, Belgium) in collaboration with von Karman Institute. He continued to involve turbine research activities at von Karman Institute between 2008-2012 as a senior research engineer. Currently, he is working as a senior engineer supporting the aerodynamic design team at TUSAS Engine Industries.
