摘要

1. S3F successfully produced 2D shear fields for 7 and 13.5 m/s 1.1 Significant differences in stress levels between leading and trailing edges 1.1.1t 1 order of magnitude in streamwise mean shear 1.1.2t 2 orders of magnitude in streamwise shear gradien 2. Optimized LPT geometry issues 2.1 Use of separate 5-6mm streamwise strips w/ 1-2mm gaps instead of single strip 2.2 Film heights = 1.5mm better for low speed dynamic range 3. 1.5mm-25Pa S3F developed 3.1t Produced deformation fields at flow velocities from 0.7 - 4.4 m/s 3.2t Further reduction of noise will produce shearand pressure fields.
