Contract: FA8650-09-C-2916
Award Amount: $749,905.00
 

Abstract:

A Three-Dimensional Damping (TDD) Model and an Alpha V1.1 computer code successfully developed and demonstrated in Phase-I will be further developed to include additional important processes such as unsteady heat release and sheared flows. In addition, aero-acoustics and screech tests will be conducted to obtain a set data for model validation and evaluation. BENEFIT: The proposed Three-Dimensional Damping (TDD) Model and the computer code will greatly benefit turbine engines OEM to better design screech liners and predict the acoustic modes that will be excited by the unsteady heat release. Such a model currently does not exist and will potentially replace the current lumped parameter-based screech liners design practices. The developed code will be transitioned to a turbine engine OEM that will utilize to improve their screech liners design to damp out both high and low order excited modes.
