- W2067030495 abstract "An integrated solution approach using Hamilton-Jacobi and Eikonal equations for providing turbulence length scales, sponge, numerical order and also blending control is shown to be promising. For all these aspects essentially distance functions from surfaces can be needed. Although, use of these integrated features focuses on jet noise problems and structured grids perhaps the greater potential is for more complex geometry problems with dense unstructured solution adaptive grids suited for say aircraft landing gear noise modeling. Studies are made exploring optimal scheme options in the high order Large Eddy Simulation (LES) code. Since, for jets, being able to model the initial shear layer instability is important, the propagation of a Tollmien-Schlichting (TS) wave is considered. Comparison with an exact analytical solution of the Orr-Sommerfeld equation for the TS wave is made. On relatively coarse grids (intended to most strongly test the discretization) the code gave excellent agreement with the analytical TS data. The code is also found to propagate well the TS wave through distorted embedded, overset grid sections. A new hybrid Implicit LES (ILES) – Reynolds Averaged Navier Stokes (RANS) method making use of the HamiltonJacobi equation is discussed and applied to jets with co-flow. Using the hybrid ILES-RANS method, the influence of swirl, synthetic chevrons, jet eccentricity, jet external surface taper and width of the co-flow region is explored. Jet centre line velocity decay predictions show encouraging agreement with established data. Results show the co-flow region thickness has a more startling influence on potential core region length than jet eccentricity. As expected, predictions show that with co-flow the acoustic waves are directed more in the downstream direction. Predictions suggest a thick co-flow region has a strong acoustic influence and for a thin co-flow jet eccentricity has a diminished effect on the acoustic field. Mild co-flow angle (<30 and produced by nozzle external surface taper) has little effect on centerline velocity decay." @default.
