Description	Opportunity Open to U.S. Citizens and Permanent Residents Turbomachinery aerothermodynamics research focuses on developing a basic understanding of the aerothermodynamic environment associated with turbomachinery. Configurations of interest include axial-flow fans, axial- and centrifugal-flow compressors, axial- and radial-flow turbines, and high-speed single and counter-rotating propellers. Models for both the time-averaged and unsteady flows in these devices are developed. This activity includes modeling of inlet distortion, blade-row interactions, and turbine heat transfer. The mathematical equations associated with these models are solved by analytical methods or by numerical procedures. Current research activities include the development of models and associated computer codes for predicting unsteady flow phenomena associated with blade-raw interaction, turbulence and other unsteady flow phenomena such as transition and separated flows that may exist in fans, compressors, film-cooled high pressure turbines and highly-loaded low pressure turbines.
