Computational Modeling of Marine Propulsors

Abstract

This letter represents our third quarterly progress report on the subject contract for the indicated period. In addition to planned objectives stated in our last quarterly report, namely, continued efforts on the 3-D parametric Navier Stokes study of the curved blade passage problem and further validation of our 3-D panel code for marine propellers with unsteady non-uniform inflow, our focus during this period included extensions of our Navier-Stokes code to axisymmetrical flow with swirl to study the inflow velocity profile for rotor-stator blade design and to a time accurate Navier Stokes solver for 2-D unsteady flow. We have also initiated a numerical analysis of acoustic noise produced by 2-D blade-vortex interaction.
