The concentration and orientation of suspended fibers in a mixing layer are investigated numerically. Two cases (diffusive and nondiffusive) are investigated for the fiber concentration distribution. The fine structures of the instantaneous distributions under these two cases are very different due to molecular diffusion. https://www.diegojavierfares.com/amazing-find-Dinah-Lace-Front-Synthetic-Wig-by-Bobbi-Boss-limited-save/
