Join the Department of Mechanical and Aerospace Engineering for the next lecture in the Spring Seminar Series. Sheryl Grace of Boston University will discuss "The Prediction of Turbofan Fan-Stage Interaction Broadband Noise."

Interaction noise in the fan stage of a turbofan engine is now a dominant commercial engine noise source especially on approach and landing. The noise is created by the interaction of the fan wake and the fan exit guide vanes (FEGV). This talk focuses on the broadband noise caused by the turbulence in the wake. While large eddy simulations of a fan stage can be run, fast prediction methods are necessary for design. A prediction approach that utilizes classical semi-analytical methods to determine the FEGV response to turbulence and relies on machine learning to define the fan wake turbulence will be presented.

All UCF graduate students and faculty are welcome to attend.
