Biography
Dr. Strazisar has more than 30 years of experience in turbomachinery aerodynamics research and advanced measurement techniques. He has served as NASA Glenn’s Chief Scientist since 2004. In that capacity he serves as a technical advisor to the senior staff and is responsible for management of Glenn’s Independent Research and Development Fund.
Dr. Strazisar’s early work focused on the development of efficient data acquisition and analysis techniques for laser anemometer measurements in high-speed rotating machinery. Between 1981 and 1991, he was the technical leader of a research group that was focused on the acquisition and analysis of detailed compressor flow field measurements. This research group was responsible for the acquisition and analysis of laser-based non-intrusive flow field measurements in transonic axial-flow fans and compressors, a large low speed centrifugal compressor impeller, and a small high-speed centrifugal impeller. These measurements have been widely used within the international turbomachinery community to advance the basic understanding of turbomachinery fluid mechanics and for turbomachinery CFD code validation.
Since 1991, Dr. Strazisar has been a Senior Technologist responsible for the design and execution of turbomachinery experiments in support of CFD code model development and validation. From 1993-2004, he also worked with a team of researchers focused on the development of stall detection and stall control methods for high-speed compressors. This team demonstrated stall control through the use of steady and actively-controlled unsteady air injection upstream of transonic axial compressor rotors and within the diffuser of a high-speed centrifugal compressor, and has implemented a stall control system for multistage axial compressors. Between 1998 and 2004, Dr. Strazisar also worked with a team that demonstrated the application of flow control methods on blade and endwall surfaces in order to increase the aerodynamic loading of compressor stators.
