During the period of this award, the basic structure-based model for rapid distortions of homogeneous turbulence was extended to deal with slow distortions and inhomegeneities. A computer program was written to study the extended model in free-shear flows. The model was installed in NASA's INS2D code for generalized flow analysis. Mr. Maire carried out this work as part of his Phd) research. During the award period we began to explore ...
