FLUID DYNAMICS: Fluid dynamics is the science of fluids in motion–both liquids and gases. It is the flow of something, whether that be air, water, mud, lava…etc.

FLUID DYNAMICS: A sub-discipline of Fluid Dynamics is hydrodynamics. Hydrodynamics would be, for instance, studying the flight of an airplane, because it flies through the air and air is considered a fluid… just less dense.

FLUID DYNAMICS: Another sub-discipline of fluid dynamics is Hydrodynamics, the study of water and other liquids in motion. It would include, for instance studying, how a turtle or a dolphin swims.

FLUID DYNAMICS: Aerodynamics would include the study of how the dorsal fin of the white shark has dermal fibers that work like the riggings stabilize a ship’s mast. The dermal fibers stiffen the dorsal fin (the top fin) dramatically as the shark swims faster which greatly affects water flow around the shark. When increasing speed, this gives the shark great control of his roll and yaw–his movements from side-to-side.

FLUID DYNAMICS: Aerodynamics is the study of air and other gases in motion. It could involve, for example, studying the 3-5 moveable alula feathers on a bird’s leading wing edge and learning how they interact with air flow. This air flow helps the bird not to stall and drop when slowing flight speed. The alula feathers make it possible for birds to land elegantly with ease. (Look at video #4 if you need to)

DANIEL BERNOULLI: Daniel Bernoulli was born in 1740. He lived at the same time as:

DANIEL BERNOULLI: Bernoulli discovered his law by puncturing the wall of a thin pipe with an open-ended tube.  He noted that the height to which the fluid rose up the tube was related to fluid’s pressure in the pipe. When the pipe was narrow, the fluid rose high in the tube because the liquid was moving faster.

DANIEL BERNOULLI: The discovery of Bernoulli’s principle was groundbreaking. However, it was not properly used in the beginning. Soon after its publishing, physicians all over Europe began measuring patients’ blood pressure by sticking tubes directly into their patient’s blood vessels.

DANIEL BERNOULLI: More than a hundred years after Bernoulli made his discoveries, a British doctor discovered a less painful method of checking blood pressure which is still in use today.

DANIEL BERNOULLI: Bernoulli was an Italian biologist,mathematician and physicist. His “Bernoulli’s principle” became one of the greatest mathematical helps in improving aviation the world has ever known!
