The flow of fluids is important in many applications ranging from blood flow in the human body to air flow over the wing of a jet aircraft. As a result, this is a required course for mechanical ...

A metamaterial is a composite material that exhibits unique properties due to its structure, and now researchers have used one featuring a small sawtooth pattern on its surface to move and position ...

PROVIDENCE, R.I. [Brown University] — One of the most common and practically useful experiments in all of fluid dynamics involves holding an object in air or submerging it fully underwater, exposing ...
