The Navier - Stokes equations are used to describe the behaviour of fluids as they run out of a tap or
flow over the wing of a commercial jet, which makes them incredibly important to solve.
Sure, they move up and down, but that motion generates lift the same way a fixed airplane wing does: When air
flows over the wing, it moves down to follow the wing's slightly tilted surface.
Hu's experiments, for example, show everything from the thickness of ice as
it flows over a wing, the heat transfer of individual water droplets as they freeze, the irregular speed of freezing droplets on a wing or blade and the finger - like patterns of ice formation.
These mounting positions make the most of the air
flowing over the wing's surface.

For the simultaneous visualization of hemolymph
flow through the heart and ventral abdominal contractions, as well as the quantification of hemolymph
flow speeds in the lateral abdomen, mosquitoes were restrained laterally by placing pins: (1) on either side of the cervical membrane such that they crossed dorsally and restrained the mosquito between the pins and the Sylgard; (2) through non-vascular portions of each
wing after they had been teased away from the abdominal tergum; (3) between the
wings and the anterior portion of the abdomen; (4)
over the legs, entering the Sylgard posterior to the third leg pair; and (5) immediately dorsal of the longitudinal midline of the scutum (Figure 1B).
