WebFluid Mechanics - University of Florida Webwhich can directly bend the fluid element as shown in Fig. 3(a). Here, the thick blue arrows indicate the primary velocity Hessian that bends the element (i.e., the velocity gradient that changes along the eˆk direction). In the short time limit, κ1 → 0, all the terms multiplied by κ1 in Eq. (4) are negligible, so Eq. (4) can be simplified ...
