Direct Numerical Simulation of Concentration and Orientation Distribution of Fibers in a Mixing Layer

Figure 8

Orientation distribution at six positions: 1, 2, and 3 are at 𝑥^∗=228 and correspond to 𝑐=0.3, 𝑐=0.5, and 𝑐=0.7, respectively; 4, 5, and 6 are at 𝑥^∗=319 and correspond to 𝑐=0.3, 𝑐=0.5, and 𝑐=0.7, respectively. (a) Azimuthal angle 𝜙; (b) polar angle 𝜃.
