Development and Validation of a Stochastic Model for the Hydrodynamic Forcing Function from Submarine Propulsors and Appendages

Abstract

The long-term objective of this research was to develop a stochastic model for the two-point surface-pressure correlation and the related surface-pressure spectrum that uses RANS data as input. The model would have given a complete hydrodynamic forcing function for structural acoustics applications. The use of Reynolds-Averaged Navier-Stokes data as input to the model allowed the model to respond to local flow and configuration complications through the RANS modeling. Contemporary experience with RANS shows clearly that it can predict mean-field statistics for Navy applications with reasonable fidelity. The method is first-principles-based and is expected to be valid for evaluation of new designs, ones with no already accumulated experimental database.
